It means it has undergone a physical change that changes its physical properties. The substance of the matter did not change. This change in the physical property is also reversible. These are characteristics of physical change. This is different from chemical change that irreversibly changes the substance of the matter.

Eva8 [605]

Answer:

Part 1:

The mother’s genotype is ii, rr, MN

The father’s genotype is IAIA/IAi, Rr, MM

Part 2:

Approximately 1/32 (3.125%) of children can be expected to have the stated blood types.

Explanation:

Part 1:

The mother has blood types 0, Rh- and MN. Therefore, her genotype has to be ii, rr, MN.

The father has ABO type A. His ABO genotype may therefore be either IAIA or IAi, as both are compatible with type A offspring with a type 0 mother. His Rh genotype must be rr, since his Rh- child necessarily has to have inherited one r allele from each parent. Finally, his MN genotype has to be MM since both alleles are codominant.

Part 2:

Using the given data, we build the following Punnett chart:

IA R N IA r N i R N i r N

IA R M

IA R N

IA r M

IA r N

IB R M

IB R N

IB r M X

IB r N

Note that, of all 32 possible combinations, only a single one of them (marked with “X” produces a genotype which matches the desired blood type, as follows:

genotype: IBi, rr, MN

blood type: B, Rh-, MN

On the lines provided, enter the name of the target organ(s) affected by the pituitary hormone indicated. Hypothalamic nerve cal

Dennis_Churaev [7]

Produced by the anterior pituitary. It's regarded as a tropical hormone. Target cells are impacted by tropical hormones indirectly after being stimulated.

<h3>The anterior pituitary gland affects which organs?</h3>

The following organs, glands, and bodily tissues are affected by and interact with the anterior pituitary hormones: organs, muscles, and bones the growth hormone (GH). Adrenocorticotropic hormone: Adrenal gland (ACTH). thyroid hormone, which stimulates the thyroid gland (TSH).

<h3>What are the anterior pituitary gland's seven hormones?</h3>

Frontal pituitary

hormone adrenocorticotrophic (ACTH)

hormone that stimulates the thyroid (TSH)

Luteinizing agent (LH)

hormone that stimulates ovulation (FSH)

Prolactin (PRL) (PRL)

hormonal growth (GH)

MSH, or melanocytic-stimulating hormone

Because it releases hormones that regulate the thyroid, adrenal glands, ovaries, and testes, the pituitary gland is frequently referred to as the "master gland."

Explain in words the semi conservative model of DNA replication. In your answer make sure you include the end result and explain

kati45 [8]

DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.
