Which 2 events during meiosis increase GENETIC
VARIATION by ensuring that each egg and each
sperm will be unique?
Answer:
(three) crossing over, mutations caused during crossing over, and independent assortment.
Explanation:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.

How can the environment affect future generations?
Answer:
Climate change is already harming people’s health by increasing the number of extreme weather events and exacerbating air pollution, according to the study published in The Lancet medical journal. And if nothing is done to mitigate it, its impacts could burden an entire generation with disease and illness throughout their lives.

Explanation:
Data from embyros can be used to help establish evolutionary relationships. True or false
Answer:
True
Explanation:
The study of the formation and development of the embryo is very useful in evolutionary biology in order to determine similarities derived from a common ancestor (i.e. homologies). In consequence, embryology is a discipline used to establish relationships between species and higher taxa. For example, vestigial organs and/or tissues (e.g., tails in humans) can be observed in the embryos during the first stages of development. In this regard, embryology has been an important aspect of the evolutionary theory proposed by Darwin (1859) by evidencing the process of species radiation from their ancient ancestors.

what Protects the cell and controls what enters and leaves the cell
Answer:
The Cell Wall & membrane transports.
Explanation:
The cell wall is what protects the innards of a cell from foreign substances, as well as protecting the overall body. The membrane transports are cut out tunnels located in the cell wall that allows for transportation of food and other products into a cell, and the waste to be expelled.

Some cnidarians are unique in exhibiting polyp and medusa forms. How might their two body forms give them an advantage over species that have only one body form?
Answer:
Explanation:
cnidarians are mostly marine animals. they exibit alternation of generation with two different body forms. their larval stage is polyp and the maturation stage is madusa. these two different forms help them to survive. polyp stage is sessile while medusa stage is free swiming. they can get food migrate and do sexual reproduction. their are also some cniderians that exhibit only one body form. these are less suited to environment as compared to the others that haae two body forms.
50 points!
As a person exercises, this causes several body systems to work together. For 2 points each, answer the following questions: 1. Define organ system and what they are made up of to be able to do specific functions 2. Identify TWO organ systems (other than the nervous system) that would be involved in exercise. 3. Explain how the NERVOUS system would be involved in the exercise.
Answer:
The parasympathetic nervous system conserves energy as it slows down heart rate, increases intestinal and glandular activity, and relaxes the sphincter muscles of the gastrointestinal tract. It gets the nickname "rest and digest" for doing exactly so. Typically most active when sleeping, however is also the explanation for post-prandial fatigue, or being tired after eating (especially a large meal).
Explanation:
Define organ system and what they are made up of to be able to do specific functions An organ system is made of a few organs that perform multiple functions.
Identify TWO organ systems (other than the nervous system) that would be involved in exercise. parasympathetic nervous system
Explain how the NERVOUS system would be involved in the exercise.The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment.The peripheral nervous system itself is divided into two parts: the somatic nervous system and the autonomic nervous system.Each of these components plays a critical role in how the peripheral nervous system operates.
Motor neurons: Also called efferent neurons, motor neurons carry information from the brain and spinal cord to muscle fibers throughout the body. These motor neurons allow us to take physical action in response to stimuli in the environment.
Sensory neurons: Also called afferent neurons, sensory neurons carry information from the nerves to the central nervous system. It is these sensory neurons that allow us to take in sensory information and send it to the brain and spinal cord.

Why does the starch remain present and is detected by iodine in the boiled solution?
Answer:
Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. ... A blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow. I hope this helps!

How can an organism's environment affect its traits?
First, I read that so incorrectly. Awkward.
An organism's environment affects its physical and self traits by making them adapt. Charles Darwin had discovered this theory with the finches. Places that were harder to get food would make these finches physical change over evolution to help them survive. It changes the animals habits depending on their resources. If a bird eats berries but there is no berries then the bird will have to change its diet or it will die.
what is Refrigeration in food preservation
Answer:
Refrigeration in Food Preservation and Processing ... The aim of all food preservation methods is to slow down processes that cause deterioration of quality and wholesomeness.

How do moving glaciers change the surface of the earth??? please help!!!
Answer:
Glaciers are massive bodies of ice that move across the surface of the Earth like rivers. As glaciers move they change the surface of the Earth by wearing away loose rocks and soil and depositing them somewhere else.
Explanation:
Answer:
Glaciers change the surface of the earth by causing small or large amounts of material to be pushed out of the way as the glacier slides along a path set by gravity and angle of the slope it is on.

C. It is more than 2.1 million years old.
D. It is exactly 1.4 million years old.
Answer:
B
Explanation:
It is less than 1.4 million years old
Based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.
What do you mean by Fossils?Fossils may be defined as the dead and organic remains of the past organisms which are preserved deep in the soil over a long period ago.
The fossil found in area A is very recent from the evolution point of view. The deeper the layer, the oldest is the fossil.
Area A of the fossil is synthesized after the time period of 1.4 million years ago, hence the fossil present in that area would be less than 1.4 million years old.
Therefore, based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.

Will give brainliest Lions are the predator that most often hunt both wildebeest And Buffalo, what do you predict is happening to the lion population between 1960 and 1975?
Answer:
Fewer than 500 lions remain in West Africa, the study estimated. The team and a panel of lion experts used the savannah data to refine estimates of lion populations, which had ranged between 20,000 and 40,000 across Africa. Their estimate: 32,000 lions remain, down from an estimated 100,000 in 1960.
