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.

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

Answer:

TTAGCCATG

Explanation:

Deoxyribonucleic acid (DNA) is a double helix molecule made up of two complementary polynucleotide strands oriented antiparallel to each other. Each nucleotide in both DNA strands is composed of a five-carbon sugar (deoxyribose), a phosphate group and a nitrogenous base. In DNA, there are four types of nitrogenous bases: Thymine, Guanine, Adenine and Cytosine (in RNA, Uracil replace Thymine). According to the base-pairing rules, Adenine always pairs with Thymine through two hydrogen bonds, whereas Guanine always pairs with Cytosine through three hydrogen bonds.

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.

Reproduction is the second ability.

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.

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:

Succulents

Explanation:

They have a thick waxy cuticle so that water vapour does not escape easily

Some have thornes so they are not eaten by animals

There roots are very wide and shallow so that they can absorb water from the surface quickly after it rains

Their stomata open at night so that too much water vapour cannot diffuse into the air

Lipids

Explanation:

read textbook

Fatty acids are a component of lipids macromolecules.

Fatty 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.

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)

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.

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.

Todas las células no tenían pared celular. Sabemos que la célula animal es un tipo de célula que solo tiene membrana celular. Las células procariotas se originaron hace aproximadamente 3,5 mil millones de años. Los centríolos son orgánulos cilíndricos, formados por proteínas, que contribuyen en la división celular. El ADN determina las características de un organismo porque el ADN tiene toda la información sobre los organismos. La digestión celular no ocurrió en las mitocondrias. El lugar de la digestión celular son los lisosomas. En la definición de celda, la palabra estructural, se refiere a la composición y forma de la celda. La palabra eucariota significa "núcleo verdadero" y núcleo verdadero significa que la membrana rodea al núcleo.
