The correct answer is C. Submucosa. The submucosa is the layer of the GI tract that contains many of the glands that secrete digestive enzymes and hormones. It also contains blood vessels and lymphatics that play a key role in absorbing nutrients.
The mucous layer provides a protective barrier and helps to lubricate and facilitate the movement of food. The muscular layer contracts to move food along the GI tract, and the serous layer covers and protects the organs in the abdominal cavity.
What is GI tract?The GI tract, also known as the digestive system, is a group of organs that work together to break down food, absorb nutrients, and eliminate waste products from the body. The GI tract starts at the mouth and includes the esophagus, stomach, small intestine, large intestine, rectum, and anus.
The organs of the digestive system secrete a variety of enzymes and acids that help to break down food into its component parts, which are then absorbed by the body for energy and other essential functions.

group of answer A. choicesmeiosis results in haploid cells while mitosis results in diploid cells.
B. Meiosis results in haploid cells while mitosis results in diploid cells. C) Meiosis produces genetically unique cells while mitosis produces genetically
Answers
The correct response is that mitosis produces genetically identical cells, whereas meiosis produces unique genetic cells.
Option C is correct.
Why is it referred to as meiosis?Meiosis is also known as reduction division because daughter cells have half the number of chromosomes as the parent cell. A human cell, for instance, has 46 chromosomes, while the egg and sperm cells produced by meiotic division have 23.
Which is better, meiosis or mitosis?While meiosis produces cells that are genetically distinct from the parent and contain only half as much DNA, mitosis produces two genetically identical "daughter" cells from a single "parent" cell. Mitosis occurs on a regular basis in the majority of cells in the body, but some cells do so more frequently than others.

Answers
Answer:
Neurotransmitter binding increases membrane permeability and form a new action potential.
Explanation:
Neurotransmitters are specific lipid-based compounds that are used in the nervous system in chemical signal transduction. They exhibit receptor-specific functions in triggering many regions and physiological responses of the brain and spinal cord or the central nervous system (CNS).
When released into the space between the synapses called the synaptic cleft, they trigger a range of responses. On the postsynaptic cells they briefly bind to chemical receptors. This results in changes to the membrane which increases the cells' permeability to ions like Na+; a new action potential is created.

What is transcription?
A DNA segment is copied into RNA during transcription. Messenger RNA is created when specific DNA sequences are translated into RNA molecules that can encode proteins (mRNA). Non-coding RNAs are RNA molecules that contain copies of other DNA sequences (ncRNAs). Only 1% to 3% of all RNA samples are mRNA. A minimum of 80% of mammalian genomic DNA can be actively transcribed (in one or more types of cells), with the bulk of this 80% being ncRNA. In contrast, less than 2% of the human genome can be transcribed into mRNA (see Human genome Coding vs. noncoding DNA).

C. a dropped object always falls toward Earth
D. microwaves passing through the atmosphere into space
Answers
Answer:
A. the rise and fall of the tides.
C. a dropped object always falls toward Earth.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
The two phenomena which are evidence that gravitational forces are attractive includes;
I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.
II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.

The table shown below represents the number of species growing in an area that was logged using clear-cutting 45 years ago in Temagami, Ontario. Data was collected periodically over 45 years.
Describe the changes occurring in vegetation type and species diversity over the 45 years.
What does the pattern of change tell you about what is happening in this area?
Explain how the data supports your conclusion.
Answers
Here is an analysis of the changes in vegetation and species diversity based on the data:
In the first years after logging, the area was dominated by grasses, with 32 species present after 1 year. Shrubs and trees were initially absent. This indicates that grasses rapidly colonized the disturbed area after logging.
Over time, the number of grass species declined as shrubs and trees became established. Shrubs first appeared after 5 years and gradually increased, with 18 species present after 45 years. Trees were absent for the first 15 years but then increased to 24 species after 45 years.
The total number of species showed a steady increase over the 45 years, from 32 species initially to a maximum of 77 species after 45 years. This indicates that species diversity was low immediately following the disturbance but gradually recovered and surpassed the original diversity levels.
The pattern of changes suggests that after the initial disturbance of logging, grasses were the first vegetation to recover and colonize the open area. Then over time, shrubs and trees established and the plant community transitioned from grasses to shrubs to trees. This successional progression from early to later species resulted in an overall increase in species diversity as different types of plants colonized the area.
In summary, the key conclusions supported by the data are:
Grasses rapidly colonized after disturbance while shrubs and trees were initially absentShrubs and trees gradually established over time, replacing some of the grass speciesTotal species diversity increased as different vegetation types colonized, reaching maximum diversity after 45 yearsThe changes indicate a successional progression from early colonizers to later species that resulted in higher diversity.2.

Syphilis is a sexually transmitted disease
Explanation:
Syphilis is a sexually transmitted infection caused by Treponema pallidum, a spirochaete gram-negative bacterium with various subspecies. This disease is transmitted through direct contact (person to person) by different types of sexual acts. A chancre is an infectious genital lesion that is considered to be the first stage (and symptom) of syphilis. The incubation period of syphilis is 14-21 days. Syphilis can be divided into four stages: primary, secondary, latent, and tertiary. Primary syphilis produces chancres on the genitals, mouth, rectum, etc. Secondary syphilis causes rashes that occur from 2-8 weeks after the chancres. The third (latent) stage is a latent/hidden phase without noticeable symptoms. Finally, the tertiary (late) stage causes large sores within the body that affects the heart, nervous system, etc. The best manner to prevent syphilis is by practicing safe sex (e.g., by using condoms). It has been suggested that syphilis has an estimated transmission rate of 0.5–1.4% per sexual act. Syphilis doesn't have an effective treatment, but this disease can be cured in its early stages with one dose of benzathine penicillin G (administered intramuscularly).
