What is composed of cells that produce hormones and secrete them into the bloodstream?.
Endocrine glands are made up of cells that release hormones into the bloodstream.
Endocrine glands are also known as ductless glands as they release certain chemical substances called as hormones directly into the bloodstream in the body. These hormones in turn, act on certain specific target organs in order to produce a certain effect.
Endocrine glands vary in shape as well as size. The important ones are the pituitary gland, thyroid gland, parathyroid gland, adrenal or supra-renal glands, pineal gland, etc. Hormones act as chemical messengers in the body.

Would there be more ocean floor between the continents or less? Why?
Answer:
Yes there is
Explanation:
There is more ocean flooring than there is land, reason being is there is a lot more water than land. Take a look at pangea there is more water than there is land and its being stopped from reaching the core by the ocean floor and there is a lot of floor on the bottom of the ocean so yes there is more ocean floor between the continents. There is more because pangea broke off into pieces making more room for land
If a dna sequence is altered from tagctga to tagtga, what kind of mutation has occurred?.
If a DNA sequence is altered from TAGCTGA to TAGTGA, then the kind of mutation that has occurred is deletion.
In the field of biology, such a mutation in which a single nucleotide or more than one nucleotide has been removed or eliminated from the DNA sequence is referred to as a deletion mutation. In the scenario above, as the nucleotide cytosine (C) is being eliminated, hence it is a deletion mutation.
A deletion mutation can also cause an entire chromosome to disappear.
A deletion mutation might occur due to many factors. Sometimes, an environmental or chemical hazard can cause a deletion mutation. Other times, it might happen that during DNA replication, an error might occur due to which one or more nucleotides are missed during the time of replication.

The population's prevalence of the dominant allele Simply put, 1 - 0.02 = 0.98 (or 98%) represents the population's frequency of the dominant (normal) allele.
How is the homozygous dominant proportion determined?Determine the proportion of people who are homozygous for the dominant allele. We are aware that the recessive homozygote genotype frequency is q2 and equals 0.09. Accordingly, p = 1 - q p = 1 - 0.30 = 0.70 In terms of homozygote dominants, p2 = (0.70)2 = 0.49 or 49% is used.
How is the Hardy-Weinberg equation solved?The Hardy-Weinberg equation is written as p 2 + 2 p q + q 2 = 1, or p2 + 2 p q + q2 = 1. and is employed to establish the prevalence of genotypes in a certain group.

Because they lack well-defined and complex organ systems, we hypothesize that poriferans diverged from all other animals early in the evolution of animals.
The most primitive animal group, the Porifera, has an early branch on the animal phylogenetic tree, making it likely that it is Precambrian in origin. Sponge is a common name for poriferans. An early branching event in the development of animals separated the sponges and other metazoans from one another. This can be one reason why they lack a well-defined and complex organ system.
Because they lack mouths, poriferans suck water through tiny holes in their external walls. Spicules, the hard support structure of these creatures, were historically one of the primary distinguishing characteristics of sponges.

The tissue layer between the muscularis mucosae and muscularis externa of the digestive tract is the myenteric plexus.
The innermost tunic of the wall is known as the mucosa, or mucous membrane layer. It lines the lumen of the digestive tract. The mucosa is made up of epithelium, a layer of lamina propria, a loose layer of connective tissue, and the muscularis mucosa, a thin layer of smooth muscle. In some places, the mucosa forms folds that increase its surface area. The mucosa's specific cells secrete hormones, digestive enzymes, and mucus. The mucosa is the route that other glands' ducts take to reach the lumen. The epithelium in the mouth and anus is stratified squamous tissue, which provides the necessary thickness for abrasion protection. For secretion and absorption, the stomach and intestines comprise a thin, simple columnar epithelial layer.
The submucosa, a thick layer of loose connective tissue, is present around the mucosa. This stratum also contains neurons, lymphatic vessels, and blood arteries. This layer might contain glands.
