Answer:
The correct answer is - D. the bats in Europe and China were healthy.
Explanation:
The white-nose disease of bats is caused by the Pseudogymnoascus destructans or Pd fungus that found in cold mines and caves of the bat. It is a fatal disease that leads to the destruction of the bat population in the United States, in north Calorina the population was dropped up to 99 percent. The bats found in Europe and China with the Pd fungus were healthy and do not cause any fatal disease in the population.

what does cytoplasm do
Answer: What does cytoplasm do
Explanation:The cytoplasm holds the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also givies the cell its shape.
Answer:
The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.
The 3 major functions of cytoplasm:
The cytoplasm support and suspend organelles and cellular molecules. Many cellular processes also occur in the cytoplasm, such as protein synthesis, the first stage of cellular respiration (known as glycolysis), mitosis, and meiosis. The cytoplasm helps to move materials, such as hormones, around the cell and also dissolves cellular waste.Review the chart, which shows the population sizes of three African animals in 1990 and in 2000.

Answer:
Population of lions are more than cheetahs and zebras.
Explanation:
The chart provides information about the population sizes of Lions, Cheetah and Zebras. According to this information, population of lions is the greatest as compared to Cheetah and Zebras. This is due to suitable conditions for the lions such as food and shelter etc in that jungle of Africa as well as strong competitor and its aggressive behaviour make them successfully survive and increase its population in the jungle.
Fatty acids are a component of what type of macromolecule?
Answer:
Lipids
Explanation:
read textbook
Fatty acids are a component of lipids macromolecules.
Fatty acids and lipidsFatty acids are a component of lipids. Lipids are a diverse group of macromolecules that include fats, oils, phospholipids, and sterols. Fatty acids are the building blocks of lipids.
They are long hydrocarbon chains with a carboxyl group at one end. Fatty acids can be saturated (no double bonds) or unsaturated (one or more double bonds).
When combined with glycerol, fatty acids form triglycerides, the most common type of lipid used for energy storage in organisms.

Refer to Animation: Cell Signaling: Adrenaline Signaling in the Heart Muscle. Adrenaline stimulates an increase in heart rate by binding to: G proteins on the cytosolic face of the plasma membrane. adenylyl cyclase. regulatory regions in genes that code for muscle cell proteins. G protein-coupled receptors on the surface of heart muscle cells. nuclear transport proteins that allow adrenaline to be taken into the nucleus to act as a transcription factor.
Answer:
The correct answer is ''G-protein coupled receptors on the surface of cardiac muscle cells.''
Explanation:
Adrenaline is a catecholamine whose pharmacological effects occur at alpha and beta adrenergic receptors. The mechanism of action of all beta adrenergic receptors is the activation of a G protein that activates adenylyl cyclase and increases cyclic AMP production. Adrenaline by b-adrenergic stimulus increases the contractile force of the myocardium (positive inotropic action) and increases the frequency in which the myocardium contracts (positive chronotropic action), consequently there is an increase in cardiac work, with a greater demand for oxygen due to the myocardium to be able to contract. Therefore, the blood flow to the heart is indirectly increased, bringing with it a greater supply of oxygen.

Organelles are structures within the cell that perform important functions. Which of the following correctly matches
organelle with its relationship to the whole cell?
mitochondria - provides the instructions for making proteins
B nucleus - provides protection to the outside of the cell
chloroplasts - trap light energy and change it into food for the cell
cell membrane - changes the energy the cell gets from food into a form the cell can use lo
Answer:
Chloroplasts trap light energy and chnage it into food for the cell
Explanation:
In the chloroplasts is where photosynthesis occurs. Photosynthesis is the process by which plants make their own food by using carbon dioxide water and sunlight. The chlorplast traps the energy from the sunlight and then the reaction between the carbon dioxide and water can occur

Explanation:
The cells of a pineapple plant have 50 chromosomes in their nuclei. How many chromosomes are there in the male nucleus in a pineapple pollen grain?
Answer:
25 chromosomes
Explanation:
There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through the process of mitosis, they originate more sexual cells, but through the process of meiosis, they give place to haploid gametes, called sperm and egg cells, through the gametogenesis process.
Gametes´destiny is to merge during fecundation, and a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell and suffers successive mitosis to form the new organism.
Meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.
So, in the exposed example
"...cells of a pineapple plant have 50 chromosomes in their nuclei..."
These might be diploid somatic or germ cells. The number of chromosomes, 2n = 50.
Germ cells in plants suffer meiosis and produce gametes.
Gametes of plants are ovocell and pollen grains. Ovocell is the feminine gamete, while the pollen grain is the masculine gamete.
The pollen grain is haploid and its number of chromosomes n = 25.

36. Mitosis requires the chromosome to be replicated into______ copies.
a. 2
b. 6
c. 1
Answer:
Option a. "2"
Explanation:
Answer:
Mitosis requires the chromosome to be replicated into 2 copies.
option a is the answer
Explanation:
The cell separates the copied chromosomes to form two full sets (mitosis) and the cell divides into two new cells (cytokinesis). The period between cell divisions is known as 'interphase'.The genome is composed of a number of chromosomes—complexes of tightly coiled DNA that contain genetic information vital for proper cell function. Because each resultant daughter cell should be genetically identical to the parent cell, the parent cell must make a copy of each chromosome before mitosis

An object is placed at 0 on a number line. It moves 3 units to the right, then 4 units to the left, and then 6 units to the right. What is the displacement of the object?
Answer:
5
Explanation:
Distance is how far something goes and Displacement is how far it is from 0 or from the starting point. Additionally, displacement is a vector so it has a direction, in this case, left or right. To make this shorter let's just find displacement. So you're at 0 and you go 3 units to the right and so you're at positive 3 on the line. Next, you move 4 units to the left so now you're at -1. Finally, you move 6 units to the right and now you're at postive 5. Now you're +5 units away from 0 and so +5 is your displacement (5 units to the right is also correct)
Answer: +5 units or 5 units to the right (as long as it has a sign or a direction it's correct)
What is the difference between a hepatic duct and a hepatic vein?
Explanation:
The liver is connected to two large blood vessels, the hepatic artery and the portal vein. The hepatic artery carries blood from the aorta to the liver, whereas the portal vein carries blood containing the digested nutrients from the entire gastrointestinal tract, and also from the spleen and pancreas to the liver.

Which definition is the best for “semipermeable membrane
Answer: A semi-permeable membrane is that which only allows certain
substances to pass through.
Answer: A semipermeable membrane is a layer that only certain molecules can pass through. Semipermeable membranes can be both biological and artificial. Artificial semipermeable membranes include a variety of material designed for the purposes of filtration, such as those used in reverse osmosis, which only allow water to pass. The biological membranes of cells are created by two sheets of phospholipid, which contain a lipid tail attached to a polar head. The tail regions of each sheet cluster together, while the heads of the molecules point outward. The polar heads point both outward toward the environment of the cell and inward toward the cytosol. In this way, a hydrophobic region of lipid tails separates the two bodies of solution. This can be seen in the image below.
