Answer: 3. Reproducing more slowly would be a good way to take advantage of plentiful resources.
Explanation:
Hydra reproduce by both sexual and asexual modes of reproduction. In the case of asexual reproduction the bud develops on the parent body and derives nutrition from parent body, matures and finally get detached from the parent body. During asexual reproduction many buds will develop and live as an individual organism this will reduce the availability of resources like habitat, food, and others. Thus if the organism reproduces slowly then it will take advantages of many resources without experiencing the scarcity of resources.

Explain the process of DNA isolation.
Answer:
Lysis, precipitation and purification
Explanation:
DNA isolation is a molecular biology technique based on the extraction of DNA and subsequent purification to remove inhibitors that may hamper the process of amplification. DNA isolation consists of three steps:
1- Lysis: it consists of the mechanical disruption of the cell, where the nucleus is broken to release DNA. During this process, it is required to use enzymes and detergents such as Proteinase K
2- Precipitation: during this process, the DNA is precipitated by using alcohol and salt.
3- Purification: this process removes the impurities from DNA. Extraction is carried out by washing DNA with ethanol and water.
How might this change affect the structure and function of the protein?
Answer:
Explanation:
Three-dimensional folding of a protein is due to interactions among the R groups of the amino acids. Cysteine has a sulfhydryl group, which may form a disulfide bridge with another part of the polypeptide chain. Valine has no sulfhydryl group and is nonpolar, which will affect how the polypeptide will fold.
Which of the following occurs just before the cell enters the G2 stage of
the cell cycle? *
O The nuclear membrane disintegrates.
O DNA replicates
O Centrioles form
O The nucleolus divides
Answer:
DNA replicates
Explanation:
S phase (Synthesis Phase) During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids, the synthesis phase of interphase takes the longest because of the complexity of the genetic material being duplicated. Throughout interphase, nuclear DNA remains in a semi-condensed chromatin configuration
Atoms of two different elements must have o ferent

o atomic numbers.
O energy levels.
Answer:
atomic numbers
Explanation:
In order for two atoms to be different, they have to have a different number of protons. Protons are represented by the atomic number. Thus, atoms of two DIFFERENT elements must have different atomic numbers.

what's the difference between pseaudscience and science
Answer:
hope it helps..
Explanation:
Pseudoscience is differentiated from science because – although it claims to be science – pseudoscience does not adhere to accepted scientific standards, such as the scientific method, falsifiability of claims, and Mertonian norms.

Lenny accidentally drops his matchbox car into a graduated cylinder. The car has a mass of 10 grams and the water level in the cylinder rises from 41 ml to 46 ml. Determine the density of the matchbox car. The formula for density is D =
m
v
.
A) 0.5 g/ml
B) 2 g/ml
C) 15 g/ml
D) 50 g/ml
Answer:
B) = 2 g/mL
Explanation:
Given data:
Mass of car = 10 g
Volume of water = 41 mL
Volume of water+ car = 46 mL
Density of car = ?
Solution:
Density is equal to the mass of object divided by volume of object.
Formula:
d = m/v
volume of car = Volume of water+ car - Volume of water
volume of car = 46 mL - 41 mL
volume of car = 5 mL
d = 10 g/ 5 mL
d = 2 g/mL

Students in Mr. Painter's science class studied samples of pond water using a microscope. To prepare for the experiment, the students placed a drop of pond water on each microscope slide, and then covered the drop with a cover slip that was marked with a 1 mm grid. Using the microscope to view the slides, students counted how many of each type of organism they found in each 1 mm square. Finally, each student calculated the total number of each type of organisms. Their data is shown below. Which organism is the least plentiful in the pond water studied? A. amoeba B. volvox C. euglena D. paramecium
Answer:
Euglena
Explanation:
the least plentiful organism in the pond water studied. Each student found fewer euglena than any other organism.

1. Which type of reaction has water in its products?
a. Hydrolysis
b. Dehydration synthesis
2. What type of reaction uses water as a reactant?
a. Hydrolysis
b. Dehydration synthesis
Answer:
1. b. Dehydration synthesis
2. a. Hydrolysis
Explanation:
Hydrolysis is the process where water is used to break chemical bonds. Dehydration synthesis is the reverse reaction, where a bond is formed resulting in the loss of water from the molecule, so a water molecule is generated as a product.
That means that dehydration synthesis produces water, and hydrolysis uses water.
Answer:
b. Dehydration synthesis gives out water as a product.
a. Hydrolysis reaction uses water as a reactant.
Explanation:
b. Dehydration synthesis can be defined as, formation of larger molecule from small reactant, followed by loss of water from the reaction.
They are also called condensation reactions.a. Explanation: Hydrolysis, it is the reaction in which compound is interacted with water which results in the degradation of that particular compound.
Hydo means water, lysis means to dissolve or breakdown.Suppose a massive amount of salt were suddenly dumped into one region of the ocean. The movement of water would be affected by the sudden increase in salt.
Identify the changes in salinity and density.
Describe the type of ocean current that would result
Answer:no
Explanation:because salt has been taken from the ocean only
Match each tool with its influence on science
Answer:
xray - allows scientists to see dense structures
Microscope - view things that cannot be seen with the naked eye
Telescope - stars, planets and black holes
Ultrasound - see inside the body in real time
Explanation:
Xrays shows highlights dense structures within the body (bones). But is not in real time, usually there images that are captured and reviews later.
Microscope - the clue is in the name, think micro= tiny! Therefore cant be seen by the naked eye. The "scope" part of the word means to look at or observe. So put them together and you get to look at or observe tiny things.
Telescope - the first part of this word "tele", means something far away or at distance. Which gives a clue at what it does, add on the "scope" meaning of to look at or observe and you get; to look at or observe something that is far away.
Ultrasound - this is what is used to monitor the health of babies when they're still developing. It can be seen in real time.
X-rays enable researchers to observe dense formations. View objects using a microscope that is invisible to the eye. Telescope: black holes, planets, and stars see into the body in real-time using ultrasound.
What is the tool microscope's influence on science?X-rays depict the body's dense internal architecture (bones). But it's not in real-time, typically, pictures are taken and then looked at afterward.
The name of the instrument, "microscope," gives it away—think small! as a result, not visible to the eye. The word "telescope" refers to anything far out or remote in its first half.
When a baby is still developing, their health is monitored using ultrasound technology.
Therefore, view objects using a microscope that is invisible to the eye.

What does the measurement 45 N represent in the photograph?
Answer:
The magnitude(size) of a force
Explanation:
Apex
The measurement of 45 N represents the magnitude of force in the photograph.
What is force?Force is defined as a cause which is capable of changing the motion of an object. It causes an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as a direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object while torque produces change in rotational speed of an object.

How do polar bear adapt to its environment?
Answer:
Polar bears have thick fur coats that help keep them keep warm in cold conditions. They have a dense layer of fur close to the skin and an outer layer of longer fur. The inner layer isulates them against the cold. ... The skin underneath their fur is black and absorbs the heat from sunlight, helping them stay warm.
