Answer:
Tropical rainforests such as the Amazon have been said to produce so much of Earth's oxygen when in fact this is not necessarily true.
Plants do indeed use Carbon dioxide during photosynthesis and the end product is Oxygen. The amount of oxygen produced however is more or less equivalent to the amount of Carbon dioxide taken in as atoms cannot be multiplied. With Carbon dioxide comprising only 0.04% of air, the oxygen produced is not as much as one would think.
After these trees produce Oxygen, they will also use it during respiration to produce energy which means that they would be sucking in most of the oxygen that they created. This would therefore reduce the net oxygen coming from these trees.
Another thing is that when plant life dies and is decomposed, the carbon dioxide that it stored from will be released back into the atmosphere. Leaves falling and fruits eaten will have this effect as well and since this happens a lot in tropical rainforests, their net oxygen production decreases.
Which effect of the weather would most likely be studied by biologists who work in this location?
weathering and erosion of park pathways
O deterioration of the man de structures in the park
pattern and timing of leaf loss in the shade trees
exposure of rocks and minerals found in the soil

Chromosomal rearrangements are considered large-scale mutations. Point mutations are considered small-scale mutations, and are of two general types. The first is a single nucleotide-pair substitution. What occurs here
Answer:
Please find the explanation of what single nucleotide-pair substitution is below
Explanation:
Point mutation is considered a small scale mutation as stated in this question because it involves only ONE nucleotide in a sequence i.e. only one nucleotide base is changed or altered in the sequence.
Single nucleotide-pair substitution is a type of point mutation in which one (single) nucleotide base is replaced by another nucleotide base. For example, in a DNA sequence that reads: TAA GTC GGG, a mutated sequence affected by single nucleotide-pair substitution will read as follows: TAA GTC TGG
Note that in the last codon (GGG), a single nucleotide G has been replaced by another nucleotide T. Therefore, single nucleotide-pair substitution is said to have occur.

Explanation:
In a warehouse, the workers sometimes slide boxes along the floor to move them. Two boxes were sliding toward each other and crashed. The crash caused both boxes to change speed. Based on the information in the diagram, which statement is correct? In your answer, explain what the forces were like and why the boxes changed speed.
Answer:
A: Box 1 has more mass than box 2
Explanation:
The liner momentum of the boxes before and after the crash. Since the larger box has more mass then it's velocity will create a larger impact upon the smaller box because it is heavier it's speed would increase before impact and since the othe box was smaller it's speed would be slower..

How is it possible a lead of an extinct fern is found in Antarctica?
Answer:
due to the continental drift
Explanation:
The theory of continental drift states that Earth's continents moved over time (i.e., they have drifted across the Earth's surface over time). The theory of continental drift was proposed by Wegener in the early 20th century. This theory has been incorporated into the idea of plate tectonics, a theory that describes the movement of seven large plates on Earth's lithosphere three billion years ago. The discovery of an extinct Permian order of seed ferns (i.e., Glossopteridales) in the Antarctic continent is nowadays considered as a proof that continents were once joined and moved over time.

Answer:A good index fossil is one with four characteristics: it is distinctive, widespread, abundant, and limited in geologic time. Because most fossil-bearing rocks formed in the ocean, the major index fossils are marine organisms. That being said, certain land organisms are useful in young rocks and specific regions.
Explanation:
Grapes harvested and crushed into juice will often produce a fermented beverage containing alcohol. Grains (such as wheat, barley, rye, or corn) will also produce an alcoholic beverage if they are soaked and allowed to ferment. Which of the following organisms, naturally present in the environment, is the likely cause of the fermentation?
a. angiosperms
b. yeasts
c. basidiomycetes
d. ciliates
Answer:
b. yeasts
Explanation:
According to this question, certain crops and grains that contains sugar such as grapes, wheat, barley, rye etc. produce an alcoholic beverage via fermentation. This fermentation process is naturally carried out by YEAST cells.
Yeasts are fungi capable of undergoing both aerobic and anaerobic cellular respiration (fermentation) depending on the availability of oxygen. Fermentation carried out by yeasts breaks down sugar in substances to alcohol (ethanol). In other words, the sugar contents of those crops is being broken down into alcohol by fermentation process carried out by YEASTS.
There are two large endocrine glands located in the neck and upper chest region. What is their identity, and what do they regulate?
A Thymus: immune system; thyroid: growth and development
B Thyroid: immune system; thymus: growth and development
C Pancreas: blood glucose levels; adrenal: emergency response
D Adrenal: emergency response; pancreas: blood glucose levels
Answer:
A Thymus: immune system; thyroid: growth and development
Thymus comes under immune system it encompasses thyroid which is responsible for growth and development. The correct option is A.
What is thymus?A tiny gland in the lymphatic system called the thymus produces and develops T-cells, specialized white blood cells.
Your immune system fights sickness and infection with the aid of the T-cells. Before birth, your thymus gland produces the majority of your T-cells.
At the base of the neck, just below the Adam's apple, is the thyroid, a tiny, butterfly-shaped gland.
Thyroxine (T-4) and triiodothyronine are the two primary hormones produced by the thyroid gland (T-3).
Every cell in the body is influenced by these hormones. They support how quickly the body consumes carbohydrates and lipids.
Thymus is a part of the immune system and contains the thyroid, which is in charge of growth and development.
Thus, the correct option is A.

What is the correct sequence of events for the cell cycle ?
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Explanation:
The cell cycle is a four-stage procedure in which the cell enlarges (gap 1, or G1), copies its DNA (synthesis, or S), gets ready to divide (gap 2, or G2), and splits (gap 4, or S) (mitosis, or M, stage).
What is the cell cycle?Interphase, which accounts for the time between cell divisions, is made up of the stages G1, S, and G2.
A cell's growth and division are accompanied by a sequence of processes known as a cell cycle.
A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.
Therefore, in eukaryotes, the cell cycle consists of four different phases: G1, S, G2, and M divide the cell.
