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.

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.

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.

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.

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).

"The Diamond Necklace by Guy de Maupassant.Mathilde suffered ceaselessly, feeling herself born to enjoy all delicacies and all luxuries. She was distressed at the poverty of her dwelling, at the bareness of the walls, at the shabby chairs, the ugliness of the curtains. All those things, of which another woman of her rank would never even have been conscious, tortured her and made her angry. The sight of the little Breton peasant who did her humble housework aroused in her despairing regrets and bewildering dreams. She thought of silent antechambers hung with Oriental tapestry, illumined by tall bronze candelabra, and of two great footmen in knee breeches who sleep in the big armchairs, made drowsy by the oppressive heat of the stove. She thought of long reception halls hung with ancient silk, of the dainty cabinets containing priceless curiosities and of the little coquettish perfumed reception rooms made for chatting at five oclock with intimate friends, with men famous and sought after, whom all women envy and whose attention they all desire.When she sat down to dinner, before the round table covered with a tablecloth in use three days, opposite her husband, who uncovered the soup tureen and declared with a delighted air, "Ah, the good soup! I dont know anything better than that, she thought of dainty dinners, of shining silverware, of tapestry that peopled the walls with ancient personages and with strange birds flying in the midst of a fairy forest; and she thought of delicious dishes served on marvellous plates and of the whispered gallantries to which you listen with a sphinxlike smile while you are eating the pink meat of a trout or the wings of a quail.She had no gowns, no jewels, nothing.
