Fatty acids and lipids

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.

what does cytoplasm do

Answers

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.

How is a scientific law different from a scientific theoryWhat is the difference between inorganic and organic compounds?

Answers

Answer:

A scientific law predicts the results of certain initial conditions. It might predict your unborn child’s possible hair colors, or how far a baseball travels when launched at a certain angle. In contrast, a theory tries to provide the most logical explanation about why things happen as they do. Organic molecules mainly have covalent bonds whereas, in inorganic molecules, there are covalent and ionic bonds. • Inorganic molecules cannot form long chained polymers as organic molecules do.

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?

Answers

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

Answers

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

Why do sex-linked traits follow different patterns of inheritance than other
traits?

Answers

It is because the males are heterozygous in terms of sex chromosome. They carry one copy of the X chromosome and one copy of the Y chromosome. So, only a single copy of allele is enough to produce the phenotype.

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.

Answers

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.

What is the difference between a hepatic duct and a hepatic vein?​

Answers

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.

The hepatic veins carry oxygen-depleted blood from the liver to the inferior vena cava. They also transport blood that has been drained from the colon, pancreas, small intestine, and the stomach, and cleaned by the liver. These veins originate from the core vein of the liver lobule, but they do not have any valves.
The hepatic duck: A duct that carries bile from the liver into the common bile duct which conveys it to the duodenum (the upper part of the small intestine).

plz can anyone write an essay about water pollution about 1300 words

The biological or chemical change in the quality of water due to the presence of contaminants in water is called water pollution. Most of this contamination as on date is due to various human activities. In fact, humans are responsible for the mass deaths of whales and other aquatic organisms often swept ashore at different beaches in the world. There is an urgent need to look into the measures to control water pollution although a lot many efforts and schemes have already been announced by the Government in this regard. To make the students aware of this we have prepared short and long essays for students which shall inform them about water pollution and the means to minimise it.

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?

Answers

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)

5
+5 units or 5 units to the right

Choose one or more: A. a delay in the unwinding of DNA B. rapid lagging-strand synthesis but slow leading-strand synthesis C. a delay in DNA polymerase beginning synthesis D. a longer total time to replicate DNA E. inefficient Okazaki fragment joining

Answers

Answer:

C. a delay in DNA polymerase beginning synthesis

D. a longer total time to replicate DNA

Explanation:

DNA primases are RNA polymerases that play an active role during DNA replication by catalyzing the synthesis of short RNA sequences or 'primers' that are complementary to a single-stranded piece of DNA (i.e., to the DNA template). Primases are continuously required at the DNA replication fork before DNA replication can occur. Moreover, DNA polymerases always require a pre-existing primer sequence to initiate DNA chain elongation, thereby it is expected that an inefficient primase delay the DNA replication process and DNA polymerase activity.

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.
