Answer:

This question lacks options, the options are;

A) In codominance and incomplete dominance, both of the alleles are dominant.

B) In codominance and incomplete dominance, neither of the alleles are dominant.

C) In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant.

D) In codominance, neither of the alleles is dominant; in incomplete dominance, both of the alleles are dominant.

The answer is C

Explanation:

Codominance and incomplete dominance are both a type of non-mendelian inheritance pattern i.e. patterns of inheritance that do not follow mendelian principles.

- In codominance, the alleles of a gene are both dominant and hence, both express themselves simultaneously for that trait. An example is the alleles A and B of the blood group in humans where both A and B are dominant in the gene.

- In incomplete dominance, neither of the two alleles of gene is dominant and none is recessive either. This means that the two alleles blend together to form an intermediate phenotype in a heterozygous offspring. An example is the pink flower in four o'clock plants resulting from the blending of red and white alleles.

Answer:

chlorophyll

A pigment molecule in the photosystem absorbs one photon, a quantity or “packet” of light energy, at a time. A photon of light energy travels until it reaches a molecule of chlorophyll.

Explanation:

Answer:

B

Explanation:

Both traits on the left are dominant meaning the offspring would take on that trait no matter what.

Explanation:

Prokaryotes do have their genomic DNA concentrated and localized to a small area within cell. so its not accurate to say that they do not have a nucleus.

Answer:

Peptide Bonds

Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).

Explanation:

plss followed me:)

Peptide bond is the answer.

What is it?

It's a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).

Sleep well after this! Hope it helped.

Answer:

1. The daughter cells are genetically identical because they each contain the same diploid chromosome complement as the original parent cell. It can be seen in the stages shown above that mitosis maintains the chromosome number or complement of a cell.

2.  Much of the growth in an adult is attributed to the growth plate in the bones, which is line of cells at each end of the bone that divides rapidly during puberty. As the bones elongate, the muscles also elongate as they are stimulated to grow by stretching and hormonal changes. When puberty is completed, the growth plate calcifies into solid bone and can no longer grow. Muscles can continue to enlarge with athletic activities and can sometimes split with excessive force, but muscle cells typically do not continue to divide. Cells such as your skin, hair, and interior mucus surface cells continue to divide because they are in direct contact with things from the outside world. Bone marrow also continually divides to produce red and white blood cells. Many other cells in your body do not continue cell division.

3. The number of Chromosomes stay the same when the cell divides because before a cell divides it produces new copies of the Chromosomes in the nucleus so when division takes place two genetically identical 'daughter cells', containing the same genes, are formed.

4. – in cells capable of dividing, the period between cell divisions is called interphase – cells spend most of their time in interphase because this is the phase where they perform their functions (obtaining energy, synthesizing products, repair damage, fight disease, duplicate their genetic material and get ready for division)

5. Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent. Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and bacteria. Many eukaryotic organisms including plants, animals, and fungi can also reproduce asexually. In vertebrates, the most common form of asexual reproduction is parthenogenesis which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited. While all prokaryotes reproduce without the formation and fusion of gametes, mechanisms for lateral gene transfer such as conjugation, transformation and transduction can be likened to sexual reproduction in the sense of genetic recombination in meiosis.

6. Since each of the parent cell’s chromosomes were replicated during interphase, there are two copies of each chromosome in the cell during prophase. Once the chromatin has condensed into individual chromosomes, the genetically-identical chromosomes come together to form an “X” shape, called sister chromatids .

Answer:

The correct answer is -

Euglena - single-cell organism

Onion bulb - organ

Blood - tissue (connective tissue)

Explanation:

The level of organization of an organ, or organism could be cellular level, tissue level, the organ level, organ system, or a complete organism. These levels are formed by assembling the lower level of the organization.

Euglena is a single-cell eukaryotic organism found in freshwater. These organisms have a very simple level of an organism which is cellular level. The onion bulb is the organ of the onion plant composed of shortened, compressed, underground stems (tissue) that are an organ-level organization.

The blood is considered as connective tissue due to the blood cells present in the matrix called plasm thus, blood is connective tissue.

A. Crossing over

During synapsis in meiosis (when the homologous chromosomes pair together during prophase I), is when crossing over occurs, and the chromatids of the homologous pairs "cross over" and swap genetic material.

I would appreciate brainliest, if not that's ok!

Answer:

884 grams of glycogen

Explanation:

Jordan's body weight = 130 pounds

Rate of storage of glycogen per pound of bodyweight = 6.8 grams

Total grams of glycogen that Jordan can store at maximum capacity:

  bodyweight x rate of storage

      = 130  x 6.8 grams

           = 884 grams

Hence, Jordan is storing 884 grams of glycogen in her body.

Answer:

When ecologists travel to regions where they are not familiar with the plants and animals, they read field guides about the flora and fauna. Many of these guides have photographs, keys to species recognition, and descriptions of size, color, and general appearance.

3.In the same way coffee is a mixture of water caffeine and other components of coffee. It could be a homogeneous mixture (everything is completely dissolved in water or a heterogeneous mixture (some of the substances may not be fully dissolved; e.g., milk.)

Explanation:

I Couldnt Tell What were The Object aside From The coffe--or was Number 3 not coffe?? - anyways That Is all I can answer

The following mixtures are made by mixing the components with each other.

A mixture is a substance comprised of two or more additional chemical compounds or substances that do not chemically combine. It is really the physical blending of two or more substances such that they may still be distinguished from one another when combined as solutions, suspensions, or colloids. Physical means can be used to separate them. The different components of any combination are not created via any sort of chemical transformation. As a result, each component's unique qualities are unaltered.

A mixture's constituent parts also do not combine chemically to form a new material, in contrast to a compound. Instead, they just combine while retaining their individual traits. The lemonade seen above is a mixture since the ingredients are not present in predetermined amounts. Even though it has more or less sugar or lemon juice, it will still be referred to as lemonade.

Therefore, mixtures are made by mixing the components together.
