Answer:
A process of change in a population through genetic variation.
Explanation:
Evolution is the process of change in heritable characteristics of populations of organisms over several generations as it allow natural selection in it.
Genetic variation which refers to differences in gene frequencies is an important force in evolution which relies of natural selection to cause an increase or reduce gene frequencies in a population. Evolution lead to changes in genetic material of populations over time which make them to develop genes that will allow them to adapt to their environment for survival and reproduction.

A. Cellular respiration shuts down during the day while
photosynthesis occurs, and then photosynthesis shuts down at night while cellular respiration occurs.
B. Both cellular respiration and photosynthesis rates cycle up and down in similar patterns over a 24-hour cycle.
C. Oxygen levels oscillate as the light-dependent reactions of photosynthesis take place during daylight and light-independent reactions take place during nighttime.
D. Cellular respiration remains constant, while photosynthesis cycles between a very high rate in the light and zero in the dark.
Answers
Answer:
Option-D
Explanation:
Cellular respiration and photosynthesis are the two main physiological process which drives the life on Earth. Photosynthesis process leads to the synthesis of Glucose whereas Cellular respiration breakdown the Glucose molecule to form ATP molecules.
In plants, the photosynthesis process occurs in green leaves whereas cellular respiration occurs in every cell of the plant inside the mitochondria.
In the given question, the graph shows:
1. The absorption of oxygen till 6 am which is required during cellular respiration.
2. After 6 am, the level of oxygen production becomes more than oxygen absorption till 6 pm.
3. After 6 pm, no sunlight is available therefore photosynthesis does not occur. After this, the rate of cellular respiration increases that is oxygen is taken in.
Thus, Option-D is correct.

B. Hypothesize how small changes in energy use can make a significant difference in CO,
emissions.
Answers
Answer:
small changes of energy can create such a big difference in co emissions. As we use less energy the amount of harmful gases that are produced from them will lower, therefore creating a smaller amount of greenhouse gases/ CO into the atmosphere.
Consider this animal cell. The organelles in an animal cell are labeled. Part A is a structure with stacked membranes, part E represents small dots on the nucleolus, part F is a network of hollow tubes, flattened sheets, and round sacs, and part G is a bean-shaped structure with folding inside. Which organelle is responsible for producing the energy for cellular processes? organelle A organelle E organelle F organelle G
Answers
Answer:
G is a bean-shaped structure with folding inside
Explanation:
The Bean shape structure is the shape of Mitochondria, therefore it is the organelle of cellular respiration.
Kreb's Cycle and oxiadative phosphorylation are the major stages of of Cellular respiration which takes place in the mitochondria.
Cellular respiration is the process of extracting the energy as ATPs contained in foods(glucose, fatty acids, Aa) by combining them with oxygen.
Electron transport chains generate the energy for pumping protons to generate the energy, for ATPs synthesis, by enzyme ATPase synthases.

Changes in groups of organisms overtime produce variations in a population. This relates to _______.
A. Macroevolution
B. Microevolution
C. Both
Answers
C. Both.
Explanation:
Changes that occur in different groups of organisms overtime that produce variations in a population relate to both macroevolution and microevolution. Although they are different, they both relate to this subject.
Macroevolution is on a big scale. This goes over organisms ancestors, large trends, and other groups of species that may be involved. This goes over a longer bit of time and is not as in depth.
Microevolution is on small scale. This goes over the different changes that may have occurred in allele frequencies from things like genetic drift, natural selection, or mutation. This goes in much more depth and looks deeper into what type of evolution may have happened.

How does Earth's solid inner core affect seismic waves?
O A. They go faster through the inner core than the liquid outer core.
O B. It blocks S waves from passing through.
O C. They go slower through the inner core than the liquid outer core.
O D. It blocks P waves from passing through.
Answers
Earth's solid inner core affect seismic waves as they go slower through the inner core than the liquid outer core.The correct option is C.
The solid inner core affects seismic waves by slowing them down. Seismic waves are waves of energy that travel through the Earth's layers, including the solid inner core and the liquid outer core.
Seismic waves can be either P waves (primary waves) or S waves (secondary waves).P waves are compression waves that can travel through both solid and liquid material. However, S waves are transverse waves that can only travel through solid material.
Thus, option C is correct.

2 Leeuwenhoek found animalcules
Dutch biologist and microscope pioneer Antoni van Leeuwenhoek observed in the late 1600s when he proclaimed the existence of a world of microscopic “animalcules”
3 The three parts of the cell theory are as follows: (1) All living things are made up of cells, (2) Cells are the smallest units (or most basic building blocks) of life, and (3) All cells come from preexisting cells through the process of cell division.
4 Four Common Parts of a Cell
Although cells are diverse, all cells have certain parts in common. The parts include a plasma membrane, cytoplasm, ribosomes, and DNA. The plasma membrane (also called the cell membrane) is a thin coat of lipids that surrounds a cell.
5 Ribosomes are small structures where proteins are made. They are found in both prokaryotic and eukaryotic cells
6 The main role of DNA in the cell is the long-term storage of information. ... The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA.

What is the net primary productivity of the tropical rainforest if gross primary productivity in a tropical rainforest is 6 kcal/m2/yr and respiration is 3 kcal/m2/yr? A) 1.5 kcal/m2/yr B) 2 kcal/m2/yr C) 3 kcal/m2/yr D) 4 kcal/m2/yr
Answers
Answer:
Net primary productivity of the tropical rain-forest = 3 kcal/m2/yr
Explanation:
Given:
Gross primary productivity in a tropical rain-forest = 6 kcal/m2/yr .
Respiration = 3 kcal/m2/yr
Find:
Net primary productivity of the tropical rain-forest
Computation:
⇒ Net primary productivity of the tropical rain-forest = Gross primary productivity in a tropical rain-forest - Respiration
⇒ Net primary productivity of the tropical rain-forest = 6 kcal/m2/yr - 3 kcal/m2/yr
Net primary productivity of the tropical rain-forest = 3 kcal/m2/yr
