Answer:
B. Club Moss
Explanation:
Club mosses are small, terrestrial plants commonly found along walking trails or roadsides. They are classified in the Kingdom Plantae because they are eukaryotic and can make their own food.
Brown algae are protists, sea cucumbers are animals, and fairy-ring mushrooms are a type of fungus.

Answer:
it may affect the animals and other tree's.
Explanation:
it may affect animals because since it is a new tree, you might not know that it may be harmful for some animals, like maybe the berries the produce are poisonous or fruits some animals are forbidden to eat. this may be a problem because some animals may accidentally eat that fruit and possibly be injured or die.
trees need sunlight and food, if another tree hopes in suddenly there would be more competition for sunlight and water, there may also be not enough water and sunlight for all the trees to share. this is a problem because if the trees can't get enough sunlight and water, they would die and this leads to a broken home for the animals living in that tree.

A major factor in changing the frequencies of the genes in the gene pool
of a population is
A) domestication
B) migration
C) asexual reproduction
D) random mating
Answer: b
Explanation:
Genetic drift refers to these fluctuations in relative allele frequency that may occur more frequently or less frequently throughout time. Rarely occurring alleles are more likely to be lost in small populations, where genetic drift typically takes place. Thus, option B is correct.
What frequency of genes in the gene pool affect migration?Migration impacts the genetic makeup of the resident population to a greater or lesser extent, depending on the amount of migration and the difference in allele frequencies between the resident and migrant populations.
Therefore, A major factor in changing the frequencies of the genes in the gene pool of a population is migration. Gene flow is the movement of alleles through human migration from one group to another.

clasificatoin of hormones
Answer and Explanation:
Hormones are substances that administer the human body having several different and essential functions for the proper functioning of the body. There are several different types of hormones and they are classified into four groups called peptides, steroids, amines and eicosanoids.
Peptides are hormones that have 3-20 amino acids. Among these hormones we can mention insulin, glucagon and somatostatin.
Steroids are hormones produced from cholesterol. Among them we can mention Cortisol, Aldosterone and Testosterone.
Amine hormones are those that are released into the thyroid and adrenal glands. These hormones circulate freely in the blood. Among them are epinephrine and norepinephrine.
Eicosanoids are the hormones derived from arachidonate. Among them are the hormones called prostaglandins, thromboxanes and leukotrienes.

An increase in heart rate will most likely result in
O (1) a decrease in metabolic rate
O (2) an increase in pulse rate
O (3) an increase in cell division
O (4) a decrease in body temperature
Answer:
O (2) an increase in pulse rate
An increase in heart rate will most likely result in an increase in pulse rate. So, the correct answer is (B).
What is Heart?Heart is a fist shaped organ which pumps blood throughout your body present in the centre of the chest tilted slightly towards the left. It is the primary organ of the circulatory system which pump blood around the body as the heart beats. The blood sends oxygen and nutrients to all parts of the body and carries away unwanted carbon dioxide and waste products from there.
Heart has four chambers (lobes) made up of muscles- two on the left side and two on the right made up of three layers of tissue -epicardium, myocardium and endocardium. These layers are surrounded by the pericardium which a thin outer lining protecting the heart.
It circulates abut 5-8 liters of blood. Heart, blood and blood vessels together make the cardiovascular system. Blood is pumped around your body through a network of blood vessels- Arteries, Capillaries and veins. Heart has four valves which act like gates which keep the blood moving in the right direction.
Thus, an increase in heart rate will most likely result in an increase in pulse rate. So, the correct answer is (B).

In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and returns to the liver.
a. True
b. False
Answer:
The correct answer is A. The statement is true.
Explanation:
Muscle obtains ATP from glycolysis. When exercise conditions are anaerobic, glucose is degraded to lactate. Lactate is exported into the circulation and is taken up by the liver. The liver synthesizes glucose again from lactate via the gluconeogenic pathway. These two metabolic pathways that allow the coupling of the function of two tissues is what is known as the Cori cycle. The energy cost is 4 P bonds / each glucose that travels both glycolytic-gluconeogenic pathways.

Tom walked into your office and said he'd been looking forward to talking with you. He said, "I've been feeling really good lately, really good...powerful, strong." Tom, a 54-year old man, was smiling and a bit wide-eyed as he began the conversation. "I'm feeling a real sense of purpose, like I was put here to help people," he said. Tom got further into his recent revelations, going so far as to say he felt "like Jesus Christ, in a way." Tom stood up with excitement as he continued to escalate emotionally and with his gestures. At no point was he threatening, but he was far more animated than ever before. As the conversation progressed, Tom told you that he was thinking about you and how powerful you were, too. He said you were like Thor with his hammer and that the two of you could really do good in the world. Then, giggling and gleeful, he admitted that he was thinking that he actually was Jesus Christ and that he wanted you and your powerful hammer to help him save humanity from those who were trying to control him.
