The shift from the Miocene, which had greater diversity of ape species and fewer monkey species, to a living assemblage with greater diversity of monkey species and fewer ape species may be the result of __________.
Answer:
A differential ability to exploit habitats after global climate change
Explanation:
According to the evolutionary theory proposed by Darwin (1859), it is not the strongest nor the most intelligent who survive, but those that are most adaptable to change. The animals that disappeared during the Miocene, a geological epoch from around 23 million years ago to 5 million years ago, likely failed to adapt to changes in environmental (temperature and vegetation) conditions. During this epoch (Miocene), a more severe climate and coarser vegetation likely contributed to the extinction of several mammal species (e.g., species of apes) and diversification of others (e.g., the divergence between chimpanzee and hominid lineages).

Explain the energy connection between the glucose and the formation of ATP in this process
Explanation:
The process can be summarized as: glucose + oxygen → carbon dioxide + water. During this process, the energy stored in glucose is transferred to ATP. Energy is stored in the bonds between the phosphate groups (PO4-) of the ATP molecule. ... When ADP and inorganic phosphate are joined to form ATP, energy is stored.
ATP stands for Adenosine Triphosphate, and is the energy currency of the cell. The energy connection between the glucose and ATP formation is oxidization of glucose.
What is the relation between ATP formation and glucose?Two molecules of ATP are broken down for single molecule of glucose to provide energy to complete the early steps, but four molecules of ATP are produced in the next steps.
At the last of glycolysis, there is a net profit of two ATP molecules for each glucose molecule broken down.
Thus, there is an energy connection between the glucose and formation of ATP is oxidization.

Why do few plants grow in the tundra?
Answer:
In the Arctic tundra, warmth and sunlight are in short supply, even in the summer. ... Only plants with shallow root systems grow in the Arctic tundra because the permafrost prevents plants from sending their roots down past the active layer of soil. The active layer of soil is free from ice for only 50 to 90 days.
Explanation:
The harsh winter climate and lack of sunlight make it hard for plants to grow.
sunlight and warmth is a necessity for plants to grow and make nutrients to survive.

In phylum Nematoda the advancement of the one way digestive tract is found. This means
the food goes in the mouth and waste out in
(1 Point)
Answer:
Anus
Explanation:
Nematodes are roundworms that belong to the phylum NEMATODA. They are characterized by their unsegmented and bilaterally symmetrical bodies. Unlike other worms e.g flatworms, which have a two-way digestive system (food enters and waste comes out via same opening), nematodes have a unique digestive system or alimentary canal.
As rightly stated in this question, nematodes have a one-way or complete digestive tract/system. This means that they take in food through the MOUTH located at one end of their bodies and pass out waste through the ANUS located at the other end.
1. At solar noon on an equinox date what would be the Sun's altitude if the latitude of NYC is 41 degrees north?
Answer: this exact measurement of solar altitude varies depending on your latitude and the time of year. If your latitude is 44 degrees north, the solar altitude at solar noon during an equinox will be 90 minus 44, or 46 degrees. During the summer solstice, the solar altitude at solar noon will be 69.5 degrees.

the question(s) are in the pdf :)
Answer:
1) b) hypotonic
2) a) hypertonic
3) a) water
4) a) B to A
5) c) osmosis
Explanation:
We have two compartments with water (A) and a solution in which the solvent is water and the solute is starch (B). The solutions are separated by a semipermeable membrane, which means that only the water molecules pass through the membrane.
1) In comparison with B, compartment A has a lesser amount of solute so it is hypotonic.
2) In comparison with A, compartment B has more solute (starch) so it is hypertonic.
3) The solvent is water, which dissolves the solute (starch).
4) Only the water molecules will pass through the membrane, and the molecules always move from the compartment with a higher concentration of solute (B) to the compartment with a lesser concentration of solute (A). So, the water moves from B to A.
5) The process in which the molecules of solvent move from a more concentrated solution to a less concentrated solution through a semi-permeable membrane is called osmosis.

Stars are hot objects and give off heat and light. Scientist can collect this energy and tell what two things about stars (even though we cannot observe or measure the star directly).
a.composition
b.temperature
c.exact mass
d.shape
Answer: A or c
Explanation:
Stars are hot objects and give off heat and light. Composition and exact mass are the things about stars.
What is Stars?A star is the most well-known celestial object and the main building block of galaxies. The age, distribution, and composition of a galaxy's stars can be used to determine the galaxy's history, dynamics, and evolution.
In addition, stars generate and disperse heavy elements like carbon, nitrogen, and oxygen, and their characteristics are strongly tied to those of any planetary systems that may develop around them.
The study of the origin, development, and death of stars is thus at the heart of astronomy.
Therefore, Stars are hot objects and give off heat and light. Composition and exact mass are the things about stars.
