A. increases the genetic variation
that's why individuals don't look like their partents. This process is called crossing-over
During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material - A. increases the genetic variation.
During meiosis, homologous chromosomes may exchange genetic material during a process called "crossing over."
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic materialthis results in recombination of the genetic material and creates a new genetic combination. This results in variations, which can be beneficial to the offspring providing a better survival advantage.So, the correct answer is Crossing over produces new combinations of genes on alleles, increasing genetic variation.

Define a bio-indicator species
Answer:
Bioindicators are living organisms such as plants, planktons, animals, and microbes, which are utilized to screen the health of the natural ecosystem in the environment. They are used for assessing environmental health and biogeographic changes taking place in the environment.

. In summary, elephants are a keystone species. Based on your knowledge of this term, explain in your own words why it is important to the ecology and ecosystems of Africa to save the elephant populations
Based on your knowledge of this term, the importance to the ecology and ecosystems of Africa to save the elephant populations is that It will save the economy if they can get them to a stable rate.
What is ecosystem?An ecosystem have each as well as every organism and the relation between the physical environment by which they must interact. The function of the ecosystem has to satisfy the need of the humans by supplying them services as well as goods from the nature.
Ecosystem has been the branch of the science which has deals with the study of the relationship between the living organisms and the natural phenomena. Ecosystem has the system in which the both living as well as nonliving organisms are present in the particular location.
There has been various types of the ecosystem such as the Grassland ecosystem, Tundra ecosystem, Desert ecosystem, Forest ecosystem and many more type of ecosystem is present in the environment.
Therefore, Based on your knowledge of this term, the importance to the ecology and ecosystems of Africa to save the elephant populations is that It will save the economy if they can get them to a stable rate.

[50 points... Will give brainliest] Explain how natural selection is impacted by genetic differences, variation, and survival.
Answer:
Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Green plants can make glucose.
Plants need energy to make glucose.
How do plants get this energy?
Answer:
atp or solar energy or from the sun
Explanation:
Please help!!! Happy holidays
Answer:
B. From 200 m to the surface
Explanation:
Photosynthesis is a process which is light-dependent. Therefore, regions where light availability is not sufficient or event absent will not support photosynthesis.
In the oceans, light availability decreases with increasing depth. Below, a certain depth in the ocean, light availability becomes insufficient to support photosynthesis and this is usually below 200 m. The uppermost region of the ocean from 200 m to the surface of the ocean is sufficiently illuminated to permit photosynthesis by phytoplankton and plants. This region is called the euphotic zone.
Therefore, from the attached image, the correct option is B, since it represents the euphotic zone of the ocean.

Answer:
A. The equation for photosynthesis and cellular respiration are opposites of each other.
Explanation:
Cellular Respiration:
C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis:
6CO2 + 6H2O → C6H12O6+ 6O.
Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.

Minerals are rarely used in everyday life true or false
Answer: False
Reason: We Use Minerals In our day to day life, when it comes to cooking, or burning. We use Salt to cook amazing meals, and some pots and pans have minerals built in to them so that they last longer over the years you cook with them. When we burn in the fireplace or in the backyard, some of us use coal and light it up, and sometimes, we use minerals to make buildings. In one of my neighboring towns, their City Hall has little mineral pieces built into the City Hall. I hope this helps, and happy holidays! :)

People should take shelter in an interior room without windows in a location in Florida most likely take if the local weather forecast predicts a tornado.
What do you mean by tornado?A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.
Various types of tornadoes include the multiple vortex tornado, landspout, and waterspout. Waterspouts are characterized by a spiraling funnel-shaped wind current, connecting to a large cumulus or cumulonimbus cloud.
Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms.

The endosymbiotic theory states that the mitochondria of eukaryotes are the evolutionary result of a Proto-eukaryotic cell engulfing an aerobic bacterium, which then evolved into the mitochondrion. Which characteristic of mitochondria supports this theory of development? A retention of a single layer membrane B retention of the chlorophyll pigments C retention of their own genome D retention of their own nucleus
Answer:
The correct answer is - C. retention of their own genome.
Explanation:
The endosymbiotic theory is a theory that suggests that eukaryotic cells are developed from prokaryotic cells. According to this theory, organelles like mitochondria are developed in eukaryotic cells as the result of proteo-bacteria cells engulfing aerobic bacteria.
The evidence of this theory can be seen as the mitochondria has their own genome such as circular DNA and ribosomes as the prokaryotes.

Positive feedback mechanisms are useful for which of the following situations?
A. Modulating a stimulus to stay within a defined range ·
B. Modulating a stimulus to move toward an endpoint
C. Amplifying a stimulus to move toward an endpoint
D. Amplifying a stimulus to stay within a defined range
Answer:
C. Amplifying a stimulus to move toward an endpoint
Explanation:
The mechanism of inputs and outputs are operated by biological systems. It is either it is caused by an event or it is causing a certain event. Feedback is very important in this system. Feedback loops are the paths in which a change to the system brings about an alarm that actually brings a certain result. In a positive feedback loop, the product of a reaction brings an increase in the reaction. This is carried out by amplifying effects of a product (stimulus) to move toward an endpoint.
