Please tell me how does water flow through sponges in order
Answer:
Small and tube shaped, water enters the sponge through dermal pores and flows into the atrium. Choanocyte flagella create the current to expel it through a single osculum. Note that water enters the sponge through a modified cell known as a porocyte.

The diploid number of chromosomes in a species is always what
A diploid cell always contains two complete sets of chromosomes, which is described as 2n.
What is a diploid cell?Two complete sets of chromosomes are present in a diploid cell. The majority of human cells are diploid, with 23 chromosomal pairs totaling 46 chromosomes. This consists of a pair of sex chromosomes and 22 pairs of autosomes. The mother and father each contributed one copy of each pair of chromosomes to the individual.
Through the process of mitosis, diploid cells replicate and maintain the same number of chromosomes by making a copy of each chromosome and dividing their DNA equally among their daughter cells.
Blood cells, skin cells, and muscle cells are examples of diploid cells. These cells are called somatic cells. Different organisms have different numbers of chromosomes.

1.what are three factors that affect the rate of chemical reactions?
2.select one of these factors and describe how it affects chemical reactions within our bodies.
Explanation:
The factors that affects the rate of chemical reactions are;
Nature of reactants Concentration of reactants or pressureTemperature Presence of catalystSunlightIn our body, the nature of reactants is very important. A food substance in solid form undergoes slow digestive process because it has little surface area exposure for the action of digestive chemicals. Most solid food are usually chewed in the mouth before digesting them to increase their surface area.
The increasing order of food digestion is;
lumps to granules to powder and to liquids.

Compare the effectiveness of the different antibiotic drugs and chemical disinfectants. Which seems to be better at controlling bacterial growth
Answer:
Antimicrobials are classified as selective and non-selective, selective are antibiotics, non-selective are surface disinfectants that are not used in human organisms such as antibiotics.
Explanation:
That is why antibiotics are considered more effective to inhibit the growth of bacteria, since the special antibiotic that covers a certain spectrum of bacteria is selected, that is what gives them specificity and greater effectiveness, some are bacteriocidal and others bacteriostatic, considering the former as those that generate the defined death of the bacteria, and assures us more of bacterial death or inhibition of proliferation.
The convection cycles of mantle are the main cause of movement of what part of the Earth?

The crust ( I think)
Explanation:
Cells are usually very small. Why is it an advantage to have many small cells instead of one very large cell?
Select all that apply.
b
OOOO
Having a larger volume lets the organelles float around more.
The surface area of the cell determines how much material can be moved in and out.
The larger surface area prevents material from moving in and out of the cell.
It is important for cells to be able to move material in and out of the cell.

CO2
ATP
NADH
FADH2
ATP is a product of glycolysis, pyruvate processing, and the citric acid cycle.
Glycolysis is the metabolic pathway by which glucose is degraded up to two pyruvate molecules, while energy is produced in the form of ATP and NADH.
It takes place in a series of nine reactions, each catalyzed by a specific enzyme, to form two molecules of pyruvic acid, with the production of ATP.The Krebs cycle produces the release of acetyl-CoA resulting in the formation of an acid with six carbon atoms, citric acid.
A series of sequential reactions then occur, each mediated by a specific enzyme.In one of the reactions of the cycle, a molecule of ATP is produced, this molecule as an energy intermediate can take energy in catabolic reactions or give it up in anabolic reactions.Therefore, we can conclude that ATP is a product of glycolysis, pyruvate processing, and the citric acid cycle.

What would happen if complexes I-IV of the electron transport chain pumped protons in the opposite direction?
a. Too much ATP would be synthesized.
b. None of the other answer options is correct.
c. No ATP would be synthesized.
d. There would be too many electrons in the mitochondrial matrix.
Answer:
The correct answer is - c. No ATP would be synthesized.
Explanation:
In the electron transport chain there are four complexes, complexes I-IV, pumps the protons from the matrix of the mitochondria into the intermembrane space. This is the downhill movement of the electrons that helps in synthesizing the ATP molecules.
If the complexes move or pump the electron uphill or against the gradient there would be no ATP formation as there would be no interchange of proton and electron interchange.

4. Which is a factor that keeps Earth in orbit around
the Sun?
A. the gravitational pull of the Sun
B. the orbital path of the moon
C. the continuous motion of the universe
D. Earth's changing speed and direction
Answer: A. the gravitational pull of the Sun
The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.
Which of these is a condition where the endometrial lining that is normally supposed to only be inside the uterus, ends up outside the uterus (for instance, in the pelvic cavity) and causes extreme pain during menstruation? This condition affects up to 1 in 4 women.
Answer:
Endometriosis is called the pathology
Explanation:
Endometriosis is a pathology where fibroblasts or connective tissue cells proliferate outside the fallopian tubes in the abdomen, close to the intestine, and adjacent to the ovaries, by proliferating and reducing the space between the organs, the pressure of the terminals increases nervous and during menstruation it hurts.
They are benign proliferative cell foci.

Assuming DNA is replicated correctly (so there are no mutations),
in which of the scenarios below would the gametes produced all
be genetically identical?
Answer:
None of the choices would lead to all identical gametes.
Explanation:
Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.
The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.
