What is the goal of Meiosis 1?
Answer:
In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells
Answer:
Meiosis I is the reduction division, and meiosis II is more similar to mitosis in that the sister chromatids are separated. The goal of meiosis I is to separate homologous chromosomes. The goal of meiosis II is to separate sister chromatids. In meiosis II, no DNA is duplicated as in prophase I of meiosis I.
Explanation:
HELP ME WITH THESE TWO QUESTIONS

Questions Two:
A few characteristics of a type of reproduction are shown below:
1. Occurs in all body cells
2. Two daughter cells are formed

Answer:
Here is a general idea on "How does adaptation help an organism"
Explanation:
When they adapt, they are able to survive in that kind of climate better, if they didn't, then they would die. especially in habitats they have never been in
True/False: Animal viruses can only infect animal cells.
Why do roots always grow in a downward direction, no matter which way you turn the seed or seedling?
because roots weigh more than any other plant part
because the plant’s stem begins to grow, and it pushes the roots downward
because that is the direction that roots find necessary water and nutrients
because the root contains hormones that make it grow away from the sun

What happens when an organism genome (genetic code) is incorrectly copied or changed?
Answer:
When there is a mistake in the copying of the genetic message that is permanent, a mutation has occurred. Two of the bases in DNA (Cytosine and Thymine) are the most vulnerable, and when this happens, they may pair with each other or themselves and the message is changed.

HOW DOES STRESS AFFECT YOUR FOCUS???
Hint: The shallower our breath, the less oxygen that reaches our brain, and the harder it is to focus.
1: When you are stressed you start breathing more deeply and makes it harder to focus.
2: When you are stressed more oxygen gets to your brain and makes it harder to focus.
3. When you are stressed you start breathing more deeply and that delivers more oxygen to your brain helps you focus.
4. none of these
Answer:
Ironically, stress does improve concentration for a very short period of time. This is due to the body releasing chemicals into the brain to help it focus and pushing adrenaline into the bloodstream in order to heighten the senses, which helps the body hone in and focus on tasks at hand.

how does the rock cycle support the explanation that "matter is never created or destroyed?"
Answer:
The chemical elements that make up minerals and rocks are not destroyed. This fact illustrates the principle of conservation of matter. The changes that take place in the rock cycle never destroy or create matter. The elements are just redistributed in other forms.

What is the problem with using common names in classification?
A general phobia with unfamiliar latinized scientific nomenclature has proliferated the use of common or trivial names. These names, however, can vary with geographic region, language, or individual preference often and thus, can lead to misidentification or a delay in the proper identification of a toxic plant.
Answer:
The only problem of using common names is that we cannot deduce the features of a particular organism just by looking at its name.
Explanation:
The only problem of utilizing basic names is that we can't find the highlights of a specific organic entity just by seeing its name.
