Define crossing over?
Answer:
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.
Explanation:
Mendel also wondered if the inheritance of one trait affected the inheritance
of another. He explored this possibility by performing is -
A. dihybrid crosses
B. back crosses
C. test crosses
D. monohybrid crosses
And after can y’all help me on others 3 so I can sleep it’s already 12
Answer:
A. dihybrid crosses
Explanation:
A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.
What are the two main reactants of photosynthesis
Answer:
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
Explanation:
This population of wolves lives in a forest. Climate change has caused a sudden change in the
environment. The forest is now covered in snow for long periods of time.
Using the following
vocabulary, explain how the population of wolves will change.
•Variation
•Competition
•Reproduction
•Genes/DNA
•Adaptation/Advantageous •Trait
Answer:
do to Climate change the wolfs will have to make an adaption to the cold and snowy weather . do to this the wolfs will have competition because they do not have the DNA in them to survive or know how to survive in this climate . if the wolfs do survive they can reproduce and the baby wolfs will pick up there traits . this will lead to different Variation of species
Explanation:

Which of the following statements is true?
Only somatic mutations are important to evolution because they can be inherited.
Acquired mutations are passed down from parent to offspring.
O Hereditary mutations are caused by external factors, such as radiation.
O Mutations are the most fundamental way to add new genes to a gene pool.
Answer: A,B, and C.) Only somatic mutations are important to evolution because they can be inherited. Acquired mutations are passed down from parent to offspring. Hereditary mutations are caused by external factors, such as radiation.
Explanation:
The true statement is: Mutations are the most fundamental way to add new genes to a gene pool.
A mutation is any alteration in the genetic material (i.e. nucleotide sequence) of the genome of an organism.
Mutations can be caused by both external (e.g., UV light) and endogenous (e.g., oxidative DNA damage) factors.
Mutation can be divided into somatic (body) cells and germline (gamete) cells. Only germline mutations can be inherited and pass from parents to offspring.
Acquired mutations are genetic alterations that are not present in the zygote, but are acquired sometime later in life. This type of mutation is involved in the development of cancer.
Mutations are the raw material on which natural selection operates, thus being the most important cause of evolutionary novelty.
In conclusion, mutations represent the most important source of genetic variability and a fundamental way to add new genes to a gene pool.

During the mid-1700s, advances in technology caused society to shift from agriculture
and manufacturing practices powered by human and animal laborers to practices
powered by fossil fuels. This historical shift is known as the Industrial Revolution. Which
of these is a likely result of the Industrial Revolution?
A. A decrease in consumption of fossil fuels
B. An increase in formation of new fossil fuels
C. A decrease in formation of new fossil fuels
D. An increase in consumption of fossil fuels
X Incorrect
Answer:
I think its c
Explanation:
im not exactly sure
Answer:
An increase in consumption of fossil fuels
Explanation:
How does the decrease in biodiversity impact an ecosystem?
Answer:
because the more alike species are The more they have to adapt to try and compete with one another So the more different a species is the less they have to compete
Answer:
the decrease in biodiversity may cause a significant reduction in the productivity of the ecosystem. The loss of biodiversity means genetic variations are lost and the overall genetic pool reduces.

Explain briefly HOW we have different cell types (blood, skin, muscles, nerves, etc.) *
Answer: Everybody is born with different blood cells, skin tone etc . That depends on your parents and the actual spermatozoon that got to the egg and eventually turned out to be you . That means that is up to the genes and races that you’ve been mixed with and created of . Sometimes even siblings have slight differences in their skin tone ,eye color etc . The genes and races or stuff like that, that you’re mixed with may pop up in different ways for you and your siblings i don’t know if that makes sense
