Explanation:
ionic bonds
Answer:
C) hydrogen bonds
Explanation:
DNA is constructed of two strands, consisting of sugar molecules and phosphate groups. 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

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

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.
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).

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
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.
First drag pink labels to pink targets to identify the digestive organs. then drag blue labels to blue targets to identify the source of each digestive enzyme or fluid.
Answer:
According to the diagram, the digestive organs on the pink targets includes:
a.) Liver, c) esophagus, d) gall bladder, e)Stomach, I) Small intestine j) Pancreas
The source of each digestive enzyme or fluid on the blue targets includes: b) bile, f) pepsin, g) Intestinal enzymes, h) Pancreatic juice.
Explanation:
The digestive system is the collective name used to describe the alimentary canal, accessory organs and a variety of digestive processes that takes place at different level in the canal to prepare food eaten for absorption.
Accessory organs of digestion generate various secretions which are poured into the tract to aid in the digestion of the food taken. They include: salivary gland, pancreas (secrets pancreatic juice), liver ( secrets bile), gall bladder ( stores bile).

Government health insurance plans are typically more expensive than private plans.
Private health insurance plans are typically more expensive than government plans.
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
Answer:b and c
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.

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.
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.
