Image is not available in the question. The image for the question is attached below:

Answer: A and B

Explanation:

Monosynaptic reflex arc consists of only two neurons, one motor neuron  and one sensory neuron. Monosynaptic means the presence of a single synapse of chemicals. Monosynaptic reflex Arc simple reflection that involves transferring input from the sensory neuron to the correct motor neuron through a single synapse in the spinal cord.

For example: the action of knee-je.rk reflex.

As the A refers to sensory neuron and B refers to motor neuron, sysnapse between A and B is a part of Monosynaptic reflex arc .

a specfic mutation in a certain animal leads to abnormal development of the heart and kidney, resulting in miscarriage. Why did
Otrada [13]

Answer:

These kinds of mutations are referred to as Lethal mutations

Explanation:

This type of mutation deleteriously affects the vital genes that are responsible for the core functions of the body. The heart supplies blood to the body organs for nutrients and oxygen while kidneys filter out toxins and end products of metabolism. Mutations in genes for development of these organs will be deadly.

Match the following.
valkas [14]

Answer:

1 . The stage on the first meiotic division when the homologous chromosomes move to opposite poles but the sister chromatids remain together

: b. Anaphase I

2 . The stage in the second meiotic division where sister chromatids migrate to opposite poles

: c. Anaphase II

3 . A structure on the chromosome that holds a pair of chromatids together during replication

: f. centromere

4 . A double-stranded chromosome following replication attached by a centromere

: d. chromatid

5 . A condition where non-sister chromatid of homologous chromosomes exchange genes

: e. crossing over

6 . The stage in the first meiotic division where the homologous chromosomes line up as a pair

: a. Metaphase I

7 . The stage in the second meiotic division where the chromatid pair lines up at the equator of the cell: g. Metaphase II

Explanation:

DNA replication occurs during the S phase of the interphase of the cell cycle. The replicated DNA molecules are accommodated in two sister chromatids of a chromosome that are held together by a centromere.  

During prophase I, the chromatids of a homologous chromosome pair exchange a genetic segment. This process is called crossing over. It generates recombinant chromatids with new combinations of genes.

Metaphase I of meiosis I includes the alignment of homologous pairs of chromosomes at the cell's equator. This is followed by separation and movement of homologous chromosomes to the opposite poles of the cell during anaphase I.  

Metaphase II of meiosis II includes the alignment of individual chromosomes, each with two sister chromatids, on the cell's equator. During anaphase II, splitting centromere separates the sister chromatids which then move to the opposite poles of the cell.

The more ________________ the homologous structure, the more likely they _______________ shared a common ancestor
Natali [406]

The more numbers of the homologous structure, the more likely they have recently shared a common ancestor.

Explanation:

Homologous organs are defined as those organs which do have different functions but a similar basic structure which denotes the divergent evolution. Homologous organs are seen in species that are very close to each other which are more related with each other in terms of evolution. For example, a bird is more close to each man than a fish, so do share more homologous organs common to man than fishes do. Examples of the homologous organs are hands of human and wings of birds. They have same basic structure like skeletal structure which is humerus, radius, ulna, carpals, metacarpals and phalanges. They are similar in structure but have different functions like flying in birds and gathering food in humans.
