Explanation:
True or false: A cell's DNA is replicated during the M phase of the cell cycle.
What is the diploid phase?
Answer:
In the sporophyte phase a diploid (having two sets of chromosomes) plant body grows and eventually produces spores through meiosis. These spores divide mitotically to produce haploid (having a single set of chromosomes) gamete-producing bodies called gametophytes.

archaea are more or less similar to eukaryotes than bacteria
Answer:
Although archaea superficially resemble bacteria in terms of size and cellular organization (members of both groups lack nuclei), they are surprisingly similar to eukaryotes at the molecular level. For instance, all archaea replicate their DNA and synthesize proteins using molecular machines like those of eukaryotes.
A population of lizards carry a gene for scale color in which the dominant allele produces green scales while the recessive allele codes for brown scales. In the first generation, you determine that 75% of the population is green and 25% of the population is brown. In the second generation, you determine that 50% of the population is green and 50% of the population is brown. Finally, in the third generation, you determine that 25% of the population is green and 75% of the population is brown. Which of the following correctly explains this change in the genotype frequencies?(1 point)
The lizards mate randomly with each other.
The brown color is an adaptation that is being selected by the environment.
The lizards remain isolated from other lizards, only mating with lizards in their own population.
The DNA of these lizards carries no mutations from one generation to the next.
Answer:
1) There are no mutations in the DNA of the population.
2) The brown color is an adaptation that is being selected by the environment.
3) The number of individuals displaying each phenotype in both the current generation and the offspring.
4)The recessive phenotype in this population may serve as an adaptation in this environment.
5) A population of flies that maintains a population size of at least 1 million individuals.
Explanation:

Within a population of rabbits, black fur (B) is dominant over white fur (b). A scientist observes 16% white rabbits on an island. The dominant allele frequency of this population is
Answer:
Explanation:
According to hardyweinberg principle
p+q= 1
P2+2pq+q2=1
given that
Black fur =B =p(dominant allele)
White fur =b =q (recessive allele)
q2=16%
16/100=0.16
q=√0.16
q=0.4
Since p+q=1
P=1-q
P=1-0.4
P=0.6
Therefore the allele frequency for dominant organism Black fur is 0.6
What is the difference between a specialized plant cell and a specialized animal cell?
Answer:
Explanation:
Major structural differences between a plant and an animal cell include: Plant cells have a cell wall, but animals cells do not. Chloroplasts enable plants to perform photosynthesis to make food. Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles if any are present.

match the following
(i) Stem tuber (a) minerals
(ii) Conditioned Reflex (b) Blue green algae
(iii) Blood Circulation (c) potato
(iv) Pancreas (d) chlorosis
(v) Autotrophs (e) Pavlov's Experiment
(vi) Active transport (f) Insulin
(g) William Harvey
Answer:
Stem tuber ---- Potato
Conditioned reflex ---- Pavlov's experiment
Blood circulation ---- William harvey
Pancreas ---- Insulin
Autotrophs ------ Blue green algae
Active transport ---- Minerals
Note: Chlorosis has no matching item in the list. Explanation is given below.
Explanation:
Stem tubers are plants which store their food in their stems. Potatoes are stem tubers.
Conditioned reflex is a reflex is acquired gradually by training in association with specific repeated external stimuli. For example, the Russian psychologist Ivan Pavlov's performed experiments on conditioned reflex using a dog. He demonstrated that a dog will salivate on the sound of a bell even if there is no food given to it if the ringing of the bell preceded every feeding session of the dog.
William Harvey discovered the circulation of blood and the function of the heart .
The islets of Langerhans found in the Pancreas secretes the hormone, insulin.
Autotrophs are organisms which are able to manufacture their own food, Blue green algae are examples of autotrophs.
Active transport is transport which requires expenditure of energy and occurs against the concentration gradient of the substance being transported. Because the concentration of minerals in the soil are in very low concentration, active transport is used by the root hair cells carrier proteins to move mineral ions across the membrane into the cell against the concentration gradient. ATP hydrolysis provides the energy for this process.
Chlorosis is a disease which appears as the yellowing of leaves in plants and in human a green tinging of the skin which is caused by the deficiency of minerals especially iron and manganese.
Which of the following is a function of the nucleus?
Answer:
Nucleus controls and regulates the activity of cell eg: growth, metabolism and carries the gene(structure that contain the heriditary information). nuclolie are small bodies often seen within the nucleus.
Explanation:
What is photosynthesis, and what is it's main goal?
Answer: Photosynthesis is the process of when a plant makes it's own food, and the main goal is to convert solar energy to chemical energy.
Explanation: Plants use photosynthesis by taking the sunlight, to synthesize foods from carbon dioxide and water. Since plants can't move and consume other organisms, they use photosynthesis. The formula is: [tex]6CO_2+6H_2O=C_6H_1_2O_6+6O_2[/tex].
Like I said, the main goal is converting solar energy to chemical energy then store the chemical energy for future use, for example it can be used for Chemical batteries, Natural gas, Heat, Food, etc.

Answer:
Evolution means change in the physical features of an organism.
Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

Explanation:
If a man with type AB blood and a woman with type O blood were to have children, what is the probability that a child would have the blood type O? *
100%
50%
25%
0%
which one^
Answer:
0%
Explanation:
Let's use a Punnett square to solve this problem.
A B
O AO BO
O AO BO
The Punnett square shows that 50% of their children will have the AO genotype and 50% will have the BO genotype. Neither of these genotypes give the child type O blood, so it is impossible for the child to have type O blood. The child would need two O alleles.
