Answer:
B)provide molecular or genetic information, as well as morphological information.
Explanation:
Systematics is the science of classification and phylogeny reconstruction. Studies diversity as a consequence of evolutive history and establishes the bases to reconstruct biological patterns and formulate hypotheses to explain the processes of these patterns. It reconstructs the origin and diversification of a taxon. Systematics creates systems of classification represented in a tree. Taxonomy is based on systematics.
The main goal of systematics is to solve the genealogical relationship between different species and biological groups that produces natural clusters.
Systematic considers morphological characters, as well as physiological, cytological, molecular, and behavioral characters.

How many alleles are in the gene pool?
Answer:
40 b alleles
Explanation:
Only 40 b alleles are present in the gene pool, so genetic diversity is lower. The use of gene pools allows population geneticists to see variation and the influence of natural selection in detail. A single gene may show significantly less genetic variation than the variation within the whole genome of a population

The density of a white dwarf is
Answer:
The density of a white dwarf is 1 x 109 kg/m3.
Explanation:
A typical white dwarf is half as massive as the Sun, yet only slightly bigger than Earth. An Earth-sized white dwarf has a density of 1 x 109 kg/m3. Earth itself has an average density of only 5.4 x 103 kg/m3. That means a white dwarf is 200,000 times as dense.
1 x 10⁹ kg/m³ is the density of white dwarf. It is 200000 times denser than Earth. And it is the second densest object we know after neutron star.

Explain how the adaptive changes in coat-color genes allowed mice to travel under the radar of hungry predators.
Answer:
This:
Explanation:
These adaptive changes help in ways best seen between desert mice and those who live in darker habitats. While desert mice often developed extremely light colored coats to blend best with the environment, mice who live in forest's or valleys often have darker coats to blend with foliage and trees. These coats that help camouflage with the environment protect mice in the open from being snatched by say a eagle or bird of prey. And mice who blend equally with foliage are protected more from ground predators like other small foxes or rodents

Herbicides are chemicals that kill plants by interrupting important biological processes. Different herbicides affect different plant processes. The herbicide atrazine prevents the chemical reactions that use energy from sunlight.
A plant is sprayed with atrazine.
Exposure to atrazine causes an immediate decrease in the production of two substances in plant. Select the substance.
A. DNA
B. Carbon dioxide
C. Oxygen
D. Phospholipids
Answer:
oxygen because that's one of the substance that plants produce.
You can also do this by the process of elimination. Knowing that atrazine impedes the production of substances in plants, we know that it can't be DNA and Phospholipid. Carbon Dioxide is used by plant, not produced; thus, oxygen is the answer.
A herbicide is a type of pesticide that is used for controlling the weeds so that the plants can get nourishment. They are common weed killers used to clear taw waste groups and constructional areas.
These herbicides are used for different plants and prevents the chemical reaction that makes use of energy. The plants are sprayed with the chemical called atrazine which is used to decrease the production of oxygen.Hence the option C is correct.

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. Scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. However, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. These global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. In Switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. Some biologists urge the collection of the few remaining individuals of some of the most threatened amphibian species, to preserve them if they become extinct in the wild. If such captive breeding programs could produce thousands of individuals from just a few of the remaining survivors, the species will still be threatened because of ______.
Answer:
a bottleneck effect
Explanation:
Genetic drift refers to the change in the allele frequencies in a population due to chance (random) events. The bottleneck effect, also known as population bottleneck, can be defined as a severe case of genetic drift caused by a drastic reduction in the population size. The bottleneck effect is well known to cause the loss of important genetic variation since alleles that were present in the original population are lost, thereby limiting its genetic diversity. One of the most common causes that may lead to a population bottleneck in a natural population is environmental disasters (e.g., earthquakes, floods, etc).

Bacteria break down dead organisms and cycle materials back into the environment. d. Symbiotic bacteria on the roots of legumes help supply nutrients to the plant.
Answer:
d. Symbiotic bacteria on the roots of legumes help supply nutrients to the plant.
Explanation:
Symbiotic bacteria on the roots of legumes help supply nutrients to the plant by fixing atmospheric nitrogen done by nitrogen fixing bacteria. There are some bacteria present in the roots of plants which fixes atmospheric nitrogen and convert in available form to the plants and in exchange the plant provides food and habitat to the bacteria that performs nitrogen fixation.
The diagram below represents the time a cell spends in the two main phases
of the cell cycle. In which phase does a cell spend more time?
A. Prophase
B. Mitosis
C. Meiosis
D. Interphase
Answer:b
Explanation:
The cell spends more time in the meiosis phase. Therefore, option "C" is correct.
What is meiosis?Meiosis is a type of cell division in sexually reproducing organisms, therefore, producing gametes. In this process, the number of chromosomes is reduced in the gametes. These cells are known as haploid cells. The examples are sperm and ovum.
There are two phases of meiosis: meiosis I and meiosis II. Meiosis I has four stages whereas meiosis II has three stages. In meiosis I, a cell divides into two genetically distinct haploid cells. In meiosis II, the two divided haploid cells divide further in two cells. Total four cells are produced in the process of meiosis.
Meiosis is an important cell division process in sexually reproducing organisms. It is used in the production of gametes in both males and females organisms.
Therefore, meiosis take more time than mitosis due to double stages.
