Explanation:

Edg 2020

The true statements are:

Government health insurance plans target specific groups of patients, such as the elderly, veterans, or children.

Private health insurance plans target specific groups of patients, such as the elderly, veterans, and children.

These sentences properly describe government and private health insurance. Medicare and Medicaid cover the elderly, low-income, and other categories. Insurance companies offer private health insurance plans to certain groups with varied coverage options and costs based on demographics and demands.

The question does not provide enough information to compare government and private health insurance costs. Coverage, geography, age, and individual circumstances affect costs. Thus, comparing government and private plan costs is inaccurate.

Explanation:

if 28% of the bases in a DNA strand are guanine, what percentage are thymine

Answers

Answer:

22%

Explanation:

According to Erwin Chargaff in his complementary base pairing rule, a DNA molecule consists of four nucleotide bases that pair with one another in the follow order: Adenine (A) to Thymine (T), and Guanine (G) to Cytosine (C).

According to Chargaff, the amount of Adenine in the DNA equals the amount of Thymine while the amount of Guanine in the DNA equals the amount of Cytosine. The sum of all the bases equals 100%. That is;

A + T + G + C = 100%

In this question, if 28% of the bases in a DNA strand are Guanine, the amount of Cytosine will also be 28%. Hence,

28% + 28% + A + T = 100

56% + A + T = 100

A + T = 100% - 56%

A + T = 44%

Since, A = T

A/T = 44/2

A/T = 22%

Hence, the amount of Thymine in the DNA strand will be 22%

Compare and contrast the structure and function of lysosome and golgi

Answers

Lysosomes are membrane-bound spherical vesicles which contain hydrolytic enzymes that can break down virtually all kinds of biomolecules. At the same time, Golgi bodies or Golgi apparatus is part of the cellular endomembrane system,which packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination. Lysosomes are isolated round or oval vesicular bodies while the Golgi bodies exist in a specific stack-like manner comprising of cisternae, tubules and vesicles.

While the Golgi apparatus is believed to originate from the endoplasmic reticulum, lysosomes are one of the vesicular packages of the Golgi cisternae. Golgi complex produces lysosomes as well as other secretory granules. Newly synthesized proteins, lipids, carbohydrates in association with the ER, are transported to the bioregion of the complex. They are sorted out and suitably modified in this complex; they are then packed in vesicles at trans region. Some of the granules contain hydrolytic enzymes and form lysosomes, while others are secreted for respective functions.

Between these two strands are nitrogen bases, the compounds which make up organisms' genes, with hydrogen bonds between them. Those hydrogen bonds have sometimes been seen as crucial to holding the two strands together

The burning and cutting of the trees will affect the carbon cycle by adding___________ to the atmosphere in the case of burning the trees and by not removing enough __________ from the atmosphere in the case of cuting the trees.

Answers

Answer:

The burning and cutting of the trees will affect the carbon cycle by adding carbon dioxide to the atmosphere, in the case of burning the trees and by not removing enough carbon dioxide from the atmosphere in the case of cuting the trees.

Explanation:

When burning and cutting down trees, these actions significantly alter the carbon cycle, adding carbon dioxide in the case of burning trees and preventing said carbon dioxide from being eliminated when cutting down the trees that, through the process of photosynthesis, are responsible for cleaning the atmosphere transforming carbon dioxide into oxygen.

Where these processes lead to carbon cycle stagnation in the short and long term.

Explain the connection between the oxidation of water in photosystem II of the light-dependent reactions and the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions.

Answers

Answer:

Please find the explanation below

Explanation:

This question is describing the processes involved in photosynthesis. In the light-dependent stage of photosynthesis, specifically photosystem II (PSII), water is oxidized in a process called PHOTOLYSIS OF WATER. This process produces electrons and Hydrogen ions (H+). The electrons produced via this process is accepted by NAD+ to yield NADH.

The NADH is an electron carrier produced during the light-dependent stage and used to reduce 3-phsophoglycerate (PGA) produced in the light-independent stage to glyceraldehyde-3-phosphate (G3P).

When and why does aerobic respiration occur during cellular respiration in plants?

Answers

A :-) This only happens during the day, and at night the plant only undergoes respiration, not photosynthesis. Aerobic respiration happens when there is plenty of oxygen (normal level in air is 21%). Anaerobic respiration happens where there is less oxygen than this.

The Law of Segregation states that: Question 6 options: Dominant traits will segregate with other dominant traits Genes segregate equally into gametes Recessive traits always segregate together Genes do not influence each other with regard to sorting into gametes

Answers

Answer:

Genes segregate equally into gametes

Explanation:

Gregor Mendel, due to his contribution to genetics, is referred to as the FATHER OF GENETICS. Among his contribution is the principles that governs inheritance in organisms. One of those principles is LAW OF SEGREGATION.

LAW OF SEGREGATION states that the alleles of a particular gene will separate into gametes in an equal manner. For example, in a gene Aa, each gamete produced by the organism with this gene will contain either allele A or allele a in equal proportion.
