Answer: Carbon is right
Explanation:
During photosynthesis carbon dioxide is pulled from the atmosphere and then captured into the tree's molecules and somehow it make the whole tree heavier.
what two types of nutrient are our main sources of energy ?

if you had to choose between the phrase "natural selection gives organisms what they need" vs. "natural selection chooses traits that are most successful", which one would you choose? defend your answer.
Answer:
Natural selection gives organisms what they need
Explanation:
The species constantly evolve because of the changes around them. Natural selection gives organisms what they NEED in order to survive. "Natural selection produces organisms perfectly suited to their environments".
Species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".
What is Natural Selection?Natural selection is defined as the differential survival and reproduction of individuals due to differences in phenotype which is a major mechanism of evolution, a change in the genetic properties of populations over generations.
It is the process through which populations of living organisms adapt and change where individuals in a population are inherently variable, meaning they all differ in some way. This variation means that some individuals have better adaptations to the environment than others.
Thus, species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".

What is the probability of getting dwarf plants with red
flowers in the F1 progeny?
Answer:
2/8
Explanation:
I did this before
1/8 or 12.5% is the probability of getting dwarf plants with red flowers in the F1 progeny.
What is a dihybrid cross?Dihybrid is defined as the cross observed between two characters, in which two different gene is responsible for the two particular characters.
In the given question plant height and flower color are observed. A tall pea plant with red flowers (TtRr) is crossed with another tall pea plant with white flowers (Ttrr).
Gametes: TtRr - TR, Tr, tR, and tr
Ttrr - Tr, Tr, tr, and Tr
Genotypes: Tall, Red (T_R_) = 6
Tall, white (T_rr) = 6
Dwarf, red (ttR_) = 2
Dwarf, white (ttrr) = 2
Therefore, the probability of getting dwarf plants with red flowers in the F1 progeny is 1/8 or 12.5%.

what do plants produce using nitrogen?
Answer: Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins.

at the cellular level, what caused Sally's cancer
Answer:
Uncontrollable cell division.
Explanation:
Cancer is a disease which is caused when cells division is uncontrollable and spread into surrounding cells and tissues. Mutations in genes is also responsible for the cause of cancer because this mutation accelerate the rate of cell division or inhibiting normal controls on the system, such as programmed cell death. When the mass of cancerous cells grows with the passage of time, it turn into a tumor.
Lack of which factor would be most likely to turn an alien species into an invasive species?
mates
suitable food
suitable habitat
predators
Answer:
predators
Explanation:
The correct answer is predators. An alien species that finds plenty of food and suitable habitat in its new home is usually able to find mates and reproduce well. But the competing species may become endangered or even extinct, because the alien (now invasive) species has no natural predators in the new environment, and its population can therefore grow without limits.
Answer: predators

While looking at a cell under a microscope you notice there is no nucleus and the
chromosomes are double stranded (they have 2 sister chromatids). What phase of mitosis is
the cell probably in?
Answer:
This is the Prophase. Mitotic Prophase,
Explanation:
The process cell division where the cells divides two similar daughter cells(2n) is called mitosis. Therefore it is called a multiplication division because two daughter cells are form from a single the mother cells. Each of the daughter cells can also undergo Futher divisions.
It is the second stage fist mitotic cells division after the first phase called Interphase.
In this stage, the nuclear membrane disappear, nucleolus disintegrate and the nucleus disappeared This is followed by the constriction of the chromosome to sister chromatids.
The constricted nuclear membrane leads to the releases of the chromatids This is followed by the formation of the spindles fibers which are needed for the movement of chromosome for cross over.
other phases are Interphase Prophase Metaphase Anaphase Telephase(IPMAT)
2. "Natural selection is usually thought of as an agent of change in populations, but it can also act to maintain the status quo."
In a short, written response, analyze and evaluate this statement. Include the range of responses of a population to changes in the environment, such as differential reproductive success, the adaptation and development of diversity in and among species, and the change in populations.
Answer:
Those organisms survive and maintain its population who are chosen by natural selection.
Explanation:
This statement means that when the population experiences a new set of environmental conditions, two things are happened i. e. the population either adjusts through natural selection or becomes extinct. The fossil of dinosaur indicates that extinction occur due to changed in the environment. If the population made changes in itself and adapt the environment then the organism survive otherwise extinction occur.
What is the ingroup in a cladogram?
Answer:
•Ingroup in biology is a group of taxa that is considered in determining evolutionary relationships. The taxa in an ingroup are closely related. In fact, they are sister groups, and they share a common ancestor. Therefore, taxa in an ingroup are descendants that split from the same node in the cladogram.

Answer:
Due to suitable environment of the equator.
Explanation:
Latitude is abiotic factor that has a great impact on the occurrence of fish species as we can see in the graph, the fish species increases as we go towards equator whereas decreases when we go away from the equator. This is because the climatic condition and temperature of water at the equator is suitable and warm so this suitable environment attracts more species to lives there.
