Answers
Answer:
Based on the relative volumes of the gases in Earth’s atmosphere, nitrogen is actually more than 3 times more than oxygen. Because the troposphere is the lowest atmosphere layer, it contains 75 percent of the atmosphere’s mass..

I’ll give brainiest:)
Answers
Answer:
The answer is C
Explanation:
I just got it right on the quiz
Fructose feeds sperm, enabling them to survive long enough to fertilize an egg.
Semen contains fructose because it feeds the sperm, enabling them to survive long enough to fertilize an egg. Therefore, the correct answer is option C.
What is fructose?Fructose is a type of sugar that provides energy to the sperm as they travel through the female reproductive tract in search of an egg to fertilize. Sperm have a limited lifespan outside the male body, so it is essential that they are supplied with enough energy to reach and fertilize an egg before they die.
The fructose in semen provides this energy to the sperm, allowing them to survive and swim towards the egg. Once inside the female reproductive tract, the fructose is absorbed by the sperm and used to fuel their movement towards the egg. Without the fructose in semen, the sperm may not have enough energy to reach the egg and fertilize it.

1. Which of the following statements about classification of organisms is true?
A: Phylogenetic classification uses genetics and ancestral relationships to classify organisms.
B: The Linnaean system of classification takes into account ancestral relationships between organisms
C: Linnaeus concentrated on the genetic characteristics of organisms to classify them.
D:In phylogenetic classification, the group that organisms are put into is called a taxon.
Answers
Answer:
Phylogenetic classification uses genetics and ancestral relationships to classify organisms.
Explanation:
took the test
The correct option is (a) Phylogenetic classification uses genetics and ancestral relationships to classify organisms.
Phylogeny classifies species based on evolutionary kinship or evolutionary distance (taxonomy). The degree and type of evolutionary distance between organisms determines their phylogenetic connection. Let's define taxonomy in order to better comprehend this idea.The connection between classification and phylogeny?The study and comparison of traits as well as the comparison of groups of organisms are the foundations of both phylogeny and categorization. However, there is a distinct feedback between character interpretation and inferred phylogeny, which is seen in the weighting of the characters used to construct the classification.

Answers
Answer:

Explanation:

As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated.

Scientists have noticed that the entire DNA molecule has the same width, despite the fact that the four nucleotides are NOT the same width Now that you’ve created a model, explain why this makes sense (hint: it has to do with the number of rings for each nitrogen base)
Answers
I don't have access to your model, although I'm sure it's beautiful. Fortunately, this question can be answered without one.
A strand of DNA is a polymer consisting of monomeric nucleotide units. The nucleotides that are found in DNA are distinguished by their nucleobases: adenine (A), thymine (T), guanine (G), and cytosine (C). Each nucleotide in DNA is made up of a single nucleobase, a sugar (deoxyribose), and a phosphate group. These nucleotides form extremely long chains comprising phosphate-sugar linkages (covalent, phosphodiester bonds).
In native, double-stranded DNA, you have of these chains (or strands) arranged side-by-side such that the nucleobases on one chain are faced directly across corresponding nucleobases on the other chain, which enables hydrogen bonding between the bases.
There is a "rule" regarding which bases form hydrogen bonds with one another (Chargaff's rule): adenine with thymine and guanine with cytosine.
What does this have to do with the width of the DNA molecule?
The four nucleotides can be structurally classified into two categories: pyrimidines and purines. For our purposes, we only need to know that pyrimidines are six-membered rings and purines are a fusion of a six- and five-membered ring (basically, purines are pyrimidines attached to a five-membered ring). Thymine and cytosine are pyrimidines, and adenine and guanine are purines.
So, geometrically, adenine and guanine are larger (and, thus, "wider") than thymine and cytosine since adenine and guanine contain an extra ring. But remember our base-pairing rules: In native DNA, adenine (two rings) on one strand pairs up with thymine (one ring) on the other strand, and guanine (two rings) pairs up with cytosine (one ring) on the other strand.
Because there's a 1:1 ratio between A:T and G:C in double-stranded DNA, the DNA molecule consists of complementary base pairs that, in any given composition of, has equivalent widths. Put simply, the A=T pair has the same width as a G≡C pair because both base pairs are between one pyrimidine and one purine.
DNA (Deoxyribonucleic acid) is composed of four nucleotides, namely, adenine, guanine, cytosine, and thymine.
Adenine and guanine are purines while Cytosine and thymine are pyrimidines.Purines are composed of two rings while pyrimidines are composed of only one ring.Purine forms bond with pyrimidine, i.e Adenine binds with thymine and guanine binds with cytosine.Adenine and thymine form two hydrogen bonds while guanine and cytosine form three hydrogen bonds.Thus, the relative pairing of the purine and pyrimidine with each other keeps the width of the DNA constant.

Conclude: An organism that breaks down organic matter into simpler materials (like carbon dioxide) is called a decomposer. Decomposers absorb nutrients from living things or the organic matter they leave behind. They do not need to kill to get their food.
Do your results suggest bears are decomposers? Explain your reasoning.
Answers
Answer:
No, because bears kill to get their food. They eat fish and they kill the fish to get them. If they left the fish carcass, decomposers would eat it. The bear makes the food for the decomposers, but it is not a decomposer itself... Does that make sense?

What best explains why, in early spring, ice remains longer on Lake Erie than on the surrounding land areas when the air temperature is above freezing?
Answers
Answer:
Because the water-specific heat is much higher than land specific -heat.
Explanation:
When water solidifies due to the temperature descent, it forms hydrogen bridges between water molecules, separating them from each other. This is the reason for water expansion during the freezing process. To go back to the liquid state, and break down the hydrogen bridges, too much heat is needed. This means that water has high water-specific heat.
Water-specific heat is the amount of energy in the form of heat needed to raise the temperature of one gram of water one degree Celsius.
Due to its high specific heat capacity, water reduces the temperature changes. For instance, when we are at the river or sea, during sunset, it gets colder because the sun is not heating directly the earth anymore. However, if we touch the water it seems to be warmer. This is because the water calorific capacity is about five times higher than the sand calorific capacity. The land gets colder faster than the water.
In the same way, when a water body such as a lake is frozen, and there is also ice on the land surface surrounding the lake, and the environment rises its temperature, first the ice on the land defrost and then, after a certain lapse of time, the ice of the water surface also defrosts.
