#CarryOnLearningUnicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function.
Unicellular organisms include bacteria, protists, and yeast.
a. Why do you think unicellular organisms perform asexual reproduction? (give two reasons)
b. What type of asexual reproduction do bacteria most commonly use?
Answer:
A)
1: The offspring of the cell will contain the exact genes of the parent by reproducing asexually
2: They can reproduce rapidly by reproducing asexually.
B) Binary fission. One cell simply splits into two identical cells.

which is a nonmendelian trait
Answer:
Polygenic traits are considered non-Mendelian because their alleles are located on more than one gene which allows for more alleles and phenotypes.
Explanation:
Examples of polygenic traits are hair color and height. Other traits, such as blood type, show codominance, where there is no dominant or recessive allele.

The reason that the mail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis
Complete question:
True or False: The reason that the nail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis.
Answer:
False
Explanation:
Nails are composed of the lamina, which is a smooth, shiny, translucent, and keratinized structure. The nails are born the nail matrix. The newly formed nail slice along the mail bed, which is the plane surface under the nails.
The nail bed places under the nail and is composed of a thin epithelium, with no granulous stratum, and a few layers of parakeratotic cells attached to the nail.
The nail matrix and nail bed have melanocytes. Half of the melanocytes of the matrix produce melanin, while melanocytes of the nail bed are inactive.
The nail bed is laying over many small vessels that nourish it and provides a pink color to the nails.
Neutral theory proposes that
A) molecular clocks are more reliable when the surrounding pH is close to 7.0.
B) most mutations of highly conserved DNA sequences should have no functional effect.
C) DNA is less susceptible to mutation when it codes for amino acid sequences whose side groups (or R groups) have a neutral pH.
D) DNA is less susceptible to mutation when it codes for amino acid sequences whose side groups (or R groups) have a neutral electrical charge.
E) a significant proportion of mutations are not acted upon by natural selection.
Answer:
The correct answer is E) a significant proportion of mutations are not acted upon by natural selection.
Explanation:
The neutral theory, proposed by Motoo Kimura in 1968, proposes that part of the molecular variability produced by mutations that exists in populations is natural variability, that is, a large part of the genetic variation observed in populations is due to random fluctuation of genetic variants that are neutral, on which natural selection hardly acts, so they are not an evolutionary force since they do not contribute predominantly to natural selection and proposes genetic drift as an evolutionary mechanism.
How do the process of DNA replication and the laws of inheritance help cells and individuals pass on their
traits?
DNA copying is otherwise known as DNA replication which is the process of producing 2 identical copies of DNA from one original DNA molecule during cell division. DNA copying is important because it generates variation during sexual reproduction which leads to evolution. Also, DNA copying helps in transfer of information or characters from the parents to the offsprings.
Mendel studied traits with only one mode of inheritance in pea plants. The inheritance of the traits he studied all followed the relatively simple pattern of dominant and recessive alleles for a single characteristic. There are several important modes of inheritance, discovered after Mendel’s work, that do not follow the dominant and recessive, single-gene model.

Does a virus have an independent lifecycle?
Which must be true for natural selection to happen?
A.) There must be genetic variation in the population.
B.) There can be no competition for resources
C.) All organisms must reproduce the same amount.
D.) The population must be below carrying capacity.
Answer:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

When 2 or more organisms compete for the same resource there can be a variety of outcomes. What would be one of those outcomes?
Answer:
The biology branch deals with the relations between and physical environment of organisms.
Explanation:
The principle of competitive exclusion states that if two species occupy the same niche, they cannot exist together (competing for identical resources). Two species whose niche overlap can evolve to have different niches through natural selection, resulting in the distribution of resources.
In ecology, interspecific competition is a form of competition where individuals from different kinds compete in an ecosystem for the same resources (e.g. food or space)... There may be interspecific competition if people of two separate species share a limited resource within a single area.

Type the correct sentence on the line below.
Answer:
Terrestrial planets are Earth, Mercury, Venus, Earth, Mars.
Explanation:
Terrestrial planets are Earth, Mercury, Venus, Earth, Mars planets whereas Jupiter, Saturn, Uranus and Neptune are Jovian planets which is also called gas giants. Terrestrial planets means that the planets have rocky soil which is hard in nature while on the other hand, a gas giant is a big planet that is composed of mainly hydrogen and helium element so we can conclude that terrestrial planets are different from gas giant in their soil composition.
In which order do organisms return
to an ecosystem during primary
succession after an area's ecosystem
has been wiped out?
A. trees, hearty shrubs, lichens
B. lichens, trees, hearty shrubs
C. lichens, hearty shrubs, trees
Answer:
lichens, hearty shrubs, trees
Explanation:
Order:
I-bare rocks,
II-pioneers (mosses, lichen, algae, fungi)
III-annual herbaceous plants
IV-perennial herbaceous plants and grasses
V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.
(please mark me brainliest) :)
Lichens, hearty shrubs, and trees is the correct order in which the organisms return to an ecosystem during primary succession after an area's ecosystem has been wiped out. Thus, the correct option is C.
What is Primary Succession?Primary succession is the ecological succession which begins in essentially the lifeless areas, such as the regions in which there is no soil or where the soil is incapable of sustaining life where no life form ever existed because of recent volcanic eruption, newly formed sand dunes, or rocks that are left from a retreating glaciers.
The correct order of the Primary Succession is:
Stage I- Bare rocks,
Stage II- Pioneer species such as mosses, lichen, algae, and fungi
Stage III- Annual herbaceous plants
Stage IV- Perennial herbaceous plants and grasses
Stage V- Shrubs, shade intolerant trees, and shade tolerant trees.
Therefore, the correct option is C.

Complete the following table on the different types of microscopes.
Answer:
A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen.
The scanning electron microscope (SEM) produces images by scanning the sample with a high-energy beam of electrons. As the electrons interact with the sample, they produce secondary electrons, backscattered electrons, and characteristic X-rays.

If both maize and teosinte are grown in the wild, which species is more likely to proliferate? Why?
Answer:
he maize is more likely to proliferate because of the human effect.
Explanation:
If both maize and teosinte are grown in the wild, teosinte is more likely to proliferate. This is because teosinte has certain adaptations that make it better suited to the wild environment.
What are maize and teosinte?Maize and teosinte are both members of the grass family, but they differ in several important ways. Maize, also known as corn, is a domesticated crop that has been selectively bred over thousands of years to produce larger, more desirable ears for human consumption. Maize has a much larger ear size than teosinte, and its kernels are also larger and more closely packed together.
Hence, if both maize and teosinte are grown in the wild, teosinte is more likely to proliferate. This is because teosinte has certain adaptations that make it better suited to the wild environment.
