Earth's atmosphere is made of different gases that can affect the Earth's Climate in different ways
True/False
Explain in full details.
Answer:
True. The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures.Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere.
The statement is true.
Effect of atmosphere on climateAtmosphere of earth contains oxygen which we use for breathing. The gases present in the atmosphere such as ozone protects us from harmful ultraviolet solar radiation.
It creates the pressure without which liquid water couldn't exist on our planet's surface. The greenhouse gases warms our planet and keeps temperatures habitable for our living Earth.

Calculate the angle of impact for a blood droplet whose width is 6.8 mm and length is 7.2 mm.
1.)94°
2.) 16°
3.) 1°
4.) 71°
Answer:
71°
Explanation:
To obtain the angle of impact :
The length of blood stain = hypotenus
The width = opposite
Hence,
Hypotenus = 7.2 mm ; Opposite = 6.8mm
Angle of impact, θ = sin^-1(opposite /hypotenus)
θ = sin^-1(6.8/7.2)
θ = 70.8°
θ = 71°
how do you think a new community begins in an area?
Answer:
community means an interacting group of various species in a common location. communities exist but new community can cause due to certain pressures either favored by the environment/nature or by humans/simply animals.
Undergoing pressures can can cause for selections such as,
-stabilizing selection
-directional selection
-disruptive selection
or may also occur due to mutations (naturally or manmade) that will further cause for a genetic drift so the nature/ the environment will help/ favor for the best fitting species to survive resulting for an evolution and will build up a new community.

Answer: I am not sure i will try to figure out
Explanation:
A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The protein can undergo a conformational change to switch between two states: either both binding sites are exposed exclusively on one side of the membrane or both binding sites are exposed exclusively on the other side of the membrane. The protein can switch between the two conformational states only if both binding sites are occupied or if both binding sites are empty, but cannot switch if only one binding site is occupied. What kind of protein do these properties define
Answer:
The protein is a symport protein.
Explanation:
Transport proteins are proteins which are involved in the transport of solutes across the cell membrane. The binding of the solute to be transported across the membrane causes a conformational change in the shape of the protein, thereby moving the molecule to the side of nthe membrane it is to be transported. The difference in the concentration of the solute across the membrane known as concentration gradient is mainly responsible for the transport of molecules by the transport proteins.
There are three types of transport proteins: uniport, symport and antiport transport proteins.
Uniporters are involved in moving only one molecule across a membrane
Symporters are involved in moving two or more molecule across a membrane in the same direction.
Antiporters are involved in moving two or more molecule across a membrane in opposite directions.
From the description of the transport protein in the question, both solutes A and B are moved across the membrane simultaneously in the same direction. Therefore, the protein is a symport protein.

In a college biology experiment, 50 mg of methane and 60 mg of sulfate are mixed in a closed container. What is the limiting reagent, and how much excess reagent remains when that species has been exhausted
Answer:
CH₄ is the excess reagent and SO₄²⁻ is the limiting reagent.
0.040 g
Explanation:
Step 1: Write the balanced reaction for the methane anaerobic oxidation
CH₄ + SO₄²⁻ ⇒ S²⁻ + CO₂ + 2 H₂O
Step 2: Establish the theoretical mass ratio between the reactants
According to the balanced equation, the theoretical mass ratio of CH₄ to SO₄²⁻ is 16.04:96.06 = 0.1670:1
Step 3: Establish the experimental mass ratio between the reactants
50 mg (0.050 g) of CH₄ react with 60 mg (0.060 g) of SO₄²⁻. The experimental mass ratio of CH₄ to SO₄²⁻ is 0.050:0.060 = 0.83:1
Comparing both mass ratios, we can deduce that CH₄ is the excess reagent and SO₄²⁻ is the limiting reagent.
Step 4: Calculate the mass excess of CH₄
The mass of CH₄ that reacts with 0.060 g of SO₄²⁻ is:
0.060 g SO₄²⁻ 16.04 g CH₄/96.06 g SO₄²⁻ = 0.010 g CH₄
The mass excess of CH₄ is:
0.050 g - 0.010 g = 0.040 g
A grass has four times the relative growth rate of a tree. But it only has double the photosynthetic rate. Please explain why the grass has such a higher RGR.
Answer:
Specific leaf area.
Explanation:
The grass has a higher relative growth rate as compared to trees because of Specific leaf area. The grass has higher growth rate due to their higher rate of photosynthesis which leads to more biomass production as compared to trees which takes too much time. The grass is able to grow faster due to environmental suitability or in other words, grasses has the ability to perform photosynthesis in every season and environment which the tree can't.

An enzyme that breaks DNA, dispels the tension, and reseals the strand ahead of a DNA replication growing fork is called a(n):
Answer:
Topoisomerase
Explanation:
Topoisomerases are enzymes that produce changes in the topology of the DNA during replication, transcription, traduction, or reparation processes. They can cut one or both strands and in order to relieve torsional stresses in the supercoiled structure of DNA. With this, they help to maintain the chromosome's integrity. There are two types of topoisomerases: topoisomerase I (it cuts only one strand of DNA) and topoisomerase II (it is able to cut both strands of DNA).

The theory of endosymbiosis is based on Multiple Choice similarities between chloroplasts and other organelles in animals. evidence from the fossil record. the knowledge that ribosomes are structures found in bacteria, plants, and animals. the experiments in which bacteria were made to grow in plant cells forming chloroplasts. the observations that chloroplasts and mitochondria resemble bacteria.
Answer:
the observations that chloroplasts and mitochondria resemble bacteria
Explanation:
The Endosymbiotic Theory is a theory that enables us to understand the origin of eukaryotic cells. The Endosymbiotic Theory posits that the mitochondria and chloroplast, which are organelles found in the eukaryotic cells, were once prokaryotic microbes that were first ingested by amoeba-like organisms and subsequently evolved by developing a symbiotic relationship with them. Some of the most important lines of evidence that supports this theory are: 1-chloroplasts and mitochondria resemble prokaryotic cells, i.e., they have a similar size, replicate by binary fission and there are unicellular eukaryotic protists that have filamentous temperature-sensitive proteins at their division plane (similarly to bacteria), and 2- chloroplasts and mitochondria are organelles with their own DNA and their own ribosomes (which are similar to those of bacteria).
Answer:
the observations that chloroplasts and mitochondria resemble bacteria
Explanation:
Replication. Mitochondria and chloroplasts make more of themselves in much the same way as bacteria reproduce. ... Like bacteria, mitochondria and chloroplasts grow in size, duplicate their DNA and other structures, and then divide into two identical organelles.

If plants are absorbing and using blue and red light, what must be happening to other colours of light, like green and yellow?
Answer:
If plants are absorbing blue and red light other colors such as green and yellow are being reflected. For example, a green plant absorbs all colors of light and reflects green, which gives it its green color.
Plants absorb and use blue and red lights during the process of photosynthesis, and the electrons get excited which carry out other pathways. While the lights like green and yellow which are not absorbed are reflected which are visible to our eyes.
What is light absorption in plants?Plants contain a pigment in the chloroplast which is known as chlorophyll. This pigment is present in all the green plants, it is responsible for trapping the light energy which comes from the Sun or artificial source.
Chlorophyll absorbs the light of different wavelengths in the visible range of light. This is known as absorption spectrum of the plant. Rest of the other wavelengths of light are reflected from the plant body which are visible to the eyes.
The wavelengths of red and blue lights show maximum rate of photosynthesis in comparison to other lights.

1. Imagine that you collected a worker ant from an ant colony, and you found that it was positive for Wolbachia. Would you expect the ant queen from that colony to also be positive for Wolbachia
Answer:
Yes.
Explanation:
Yes, the ant queen from that colony to also be positive for Wolbachia because Wolbachia also cause infection in the ant queen. This bacteria lives in the cell of their host and cause infections. This bacteria specie is responsible for the reproductive and developmental changes in the invertebrates so we can conclude that Wolbachia also affect the ant queen of that colony.

Explanation:
One way to think about the importance of biodiversity is simply to think in terms of natural capital: the roles that genes, species, ecosystems, and ecological processes play in supporting human society and a healthy biosphere. What are benefits provided by biodiversity?
Answer and Explanation:
Biodiversity composes of different species living in a certain restricted area. It is the variability of living beings in a natural environment, involving all the species on the planet and their genetic material. This variety includes all plants, animals, fungus, and microorganisms living in a certain place, their genetic variability, and the ecosystems these species form.
Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.
Biodiversity, in equilibrium with abiotic factors, provides ecosystem services, which are important for the maintenance of all forms of life, including human beings.
Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials, raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems provide a recreational place or area to spend time and learn. They provide a spiritual/religious space, are a source of inspiration. Ecosystems are cultural patrimony and the source of scientific knowledge.

Peppered Moths
Before the Industrial Revolution there were more sightings of light-colored moths and
fewer sightings of dark-colored moths. As factories were built during the Industrial
Revolution, pollution increased. At this time, scientists observed that the number of
light-colored moths decreased, while the number of dark-colore moths increased and
became more abundant in the population than the light-colored variety.
Which graph represents how natural selection acted on moth coloration during
the Industrial Revolution? The dotted line represents the original population and the
solid line represents the population after selection.
Answer:
The correct answer is - Option B.
Explanation:
Before the Industrial Revolution, the light color moths were predominant so that they can blend in with the light-colored trees and lichens in their environment. After releasing coal smoke from factories, the trees became darkened, and the light-colored moths become an easy target for predator birds to spot.
Over time, the frequency of the dark moth increased due to they had a higher survival rate in habitats affected by the air pollution and it blends with darker coloration blended with the sooty trees. This is a shift in the population’s genetic variance toward the new, phenotype.
In graph B, light color moth frequency decreases, and after natural selection increases over time and after a decrease in evolution the dark color again decreases.
