During sensation, the first step for some sensory systems is the accessory structures, which are saddled with the responsibility of modifying an incoming stimuli.
A sensory system refers to components of the central nervous system (CNS) which comprises of the brain, neural tissues (pathways) and sensory neurons that are responsible for sensory functions, perception and processing of sensory information such as light, sound, heat, etc.
Basically, the five (5) main sense organs in the sensory system include the following:

Active transport moves molecules from and to which concentration?
A: high to low
B: low to high
C: low to lower
Option (B) low to high is right Answer
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
We know that, Active transport moves ions and molecules across a membrane against the concentration gradient. It requires energy.
The characteristic features of active transport are:
-The movement of molecules in case of active transport is from lower concentration to higher concentration so it shows uphill transport.
-These have carrier proteins that are highly specific like enzymes for the substances to be carried across the membrane.
-The process of active transport can be inhibited by inhibitors that react with the protein side chains.
-The transport rate reaches its maximum when all the protein carriers are in use or get saturated with the substances to be carried.
The various types of processes that depend on active transport are:
-Absorption of amino acids from the gut.
-Absorption of mineral ions by plant roots.
-Excretion of urea and hydrogen ions by the mammalian kidney.
-Exchange of sodium and potassium ions in nerve cells.
-Filling of the contractile vacuole in amoeba.
The phloem in the leaves of a plant is rich in sugars because of the high rate of active transport.
Additional information :- Some intrinsic protein molecules function as molecular pumps. These permit the cell to go for active transport to accumulate glucose or ions against the concentration gradient. Cells that undergo active transport have abundant mitochondria that provide ATP needed to power active transport.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

A disease-causing bacteria successfully enters your body, making it past the first and second lines of defense. Which barrier will then act on the bacteria? chemical physical biological electrical.
Answer:
The correct answer is biological.
Explanation:
When any pathogen invades the body, it has to pass several lines of defence. The first barrier is the skin and mucous membrane which is a physical and chemical barrier. The second line of defence is the non-specific response by macrophages, neutrophils and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells act specifically on the pathogen and destroy it.
Answer:

Explanation:
In the 200-plus years since the industrial revolution began,concentration of carbon dioxide in the atmosphere has increased due to human actions.During this time,the pH of surface ocean waters has fallen by 0.1 pH units.This might not sound like much,but the pH scale is logarithmic,so this change represents approximately a 30 percent increase in acidility.

Which statements correctly describe mutations in gametes and mutations in somatic cells?
Mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Mutations to gametes are more likely to be beneficial than mutations to somatic cells.
Mutations to somatic cells will be inherited by an organism's offspring.
Mutations to gametes can be passed on to an organism's offspring
O Mutations to gametes do not involve changes in the DNA.
Mutations to somatic cells are transferred to daughter cells.
Answer:mutations to gametes can be passed on to an organism's offspring and mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Explanation:The mutation in the somatic cells is known as somatic mutations. As they do not take place in the cells, which give rise to gametes, thus, the mutation is not inherited to the next generation by the sexual means.
On the other hand, the genetic mutations take place in the germline cells, that is, egg and sperm, because of this the mutations possesses the tendency to get passed on from one generation to another.
Thus, mutations are only passed on to offspring when they take place in germ cell DNA. The other kind of cells, the somatic cells refers to the rest of the cells in the body and mutations, which takes place in these cells do not get inherited further to the offspring.
Hence, the correct statements are

For this discussion, explain how each organelle in a eukaryotic animal cell is interconnected with the others. You will need to write at minimum a couple of paragraphs but at most as much as it will require for you to answer this.
Answer:
Different organelles make close contacts with each other via MCSs. These contact sites are generally thought to form via membrane proteins that act as tethers on the interacting organelles . Often these tethers are part of large multiprotein complexes.
The endomembrane system (endo = within) is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins. It includes the nuclear envelope, lysosomes, vesicles, endoplasmic reticulum and the Golgi apparatus, which we will cover shortly.
There are two types of proteins: structural proteins and enzymes. Cell organelles must work together to carry out protein synthesis, utilize proteins within the cell, and transport them out of the cell.

what is the primary action of antidiuretic hormone?
Answer:
The primary action of the antidiuretic hormone is that it causes collecting ducts in the kidneys to reabsorb more water.
Explanation:
Human vasopressin is also known as the Anti-diuretic hormone (ADH) causes kidney-collecting ducts to reabsorb more water.
What is Anti-diuretic hormone (ADH)?Human vasopressin is also called antidiuretic hormone, arginine vasopressin or argipressin. It is defined as the hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus that converts to AVP.
ADH is the hormone that helps constrict blood vessels and helps the kidneys control the amount of water and salt in the body which helps control blood pressure and the amount of urine. This reduces the amount of urine released and the nature of urine becomes hypertonic which is concentrated. Because of this type of action, vasopressin is known as an antidiuretic hormone.
Thus, Human vasopressin is also known as the Anti-diuretic hormone (ADH) causes kidney-collecting ducts to reabsorb more water.
