Answer:
cess for GE crops conducted by the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), and the U.S. Food and Drug Administration (FDA). Other evidence came from studies published by regulatory agencies in other countries or by companies, nongovernmental organizations (NGOs), and academic institutions. The committee also sought evidence from the public and from the speakers at its public meetings and webinars.1
The committee thinks that it is important to make clear that there are limits to what can be known about the health effects of any food, whether non-GE or GE. If the question asked is “Is it likely that eating this food today will make me sick tomorrow?” researchers have methods of getting quantitative answers. However, if the question is “Is it likely that eating

FALSE
A sperm cell always has more mitochondria than a skin cell.
Why? The sperm's midpiece contains many mitochondria so that a supply of energy is available for the sperm to perform its function of traveling to and later fertilizing the egg.
Could u give me Brainliest answer plz
Answer:
Stratigraphy and Biostratigraphy.
Explanation:
Relative dating is a method of determination of age, in which one object or organism is compared with the other object or organism found in the heap of strata. It is a method for determining the relative order of the past events, without stating the absolute age.
Stratigraphy is a branch of geology that studies the relative position of the sediments and rocks in the strata with respect to the geological timescale. Biostratigraphy is the branch of stratigraphy which deals with the relative aging of fossils with respect to the strata in which these are found defining a particular period of geological time scale.
An atmosphere is a layer of gas or layers of gases that envelope a planet, and is held in place by the gravity of the planetary body.
Answer:
- Populations must be very large -True
- The frequency of all genotypes must be equal. False
- Gene flow from other populations must be zero. True
- Matings must be random. True
- There should be no natural selection. True
Explanation:
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- <u>Random matings</u>: mating probabilities between individuals with determined genotypes depends on the products of frequencies of those genotypes.
- No superposed generations: each individual can leave their gametes in the pool only once.
- No mutations: There is no incorporation into the genetic pool of new gametes originated by mutation of preexistent alleles.
- <u>No migration</u>: There is no incorporation of gametes originated in another population.
- <u>Infinite population size</u>: the probabilities of randomly taking an A gamete from the pool are p and the probabilities of taking a B gamete from the pool are q.
- <u>No natural selection</u>: Each individual has the same surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.
