Answer:

Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.

A litter of four kittens includes one with black hair and blue eyes, one with black hair and orange eyes, one with brown tabby h

Hoochie [10]

Answer:

Law of independent assortment

Explanation:

According to Gregor Mendel who he performed a performed a cross involving two different genes i.e. a dihybrid cross, he stated that the allele of one gene will get sorted into gametes independently of the alleles of the other gene. He called this the LAW OF INDEPENDENT ASSORTMENT.

He obtained a 9:3:3:1 ratio when he performed this cross, which was only expected if each gametes contained the two genes in a combined state i.e. the dominant allele for one gene is equally likely to contain a dominant or recessive allele for the other gene in a gamete.

In this case, it appears the black hair and blue eyes are dominant alleles respectively while the tabby hair and orange eyes are recessive alleles respectively. If these alleles assort independently and combine in different ways, it will give rise to diverse genotypes and phenotypes in the kitten as illustated in the different phenotypic expression of eye color and hair color in the kitten.

Which hypothalamic hormone contributes to the regulation of the male reproductive system? a. luteinizing hormone b. gonadotropin

Lostsunrise [7]

Answer:

The correct answer is option b. gonadotropin-releasing hormone.

Explanation:

The GnRH or the gonadotropin-releasing hormone is a releasing hormone that releases from the neurons of the hypothalamus. This releasing hormone is responsible for the secretion of the luteinizing hormone and follicle-stimulating hormone.

GnRH regulates both gonadotropin hormones, in which, LH (luteinizing hormone) responsible for the regulation of the male reproductive system and FSH (follicle-stimulating hormone) responsible for the female reproductive system and sperm production in testes in males.

Thus, the correct answer is option B. gonadotropin-releasing hormone.
