Answer:
preparation, environmental controls, and contact guidelines
Explanation:
A scientist is researching two different traits in an insect: body texture and color. Smooth body (B) is dominant to bumpy body (b), and gray (G) is dominant to white (g). A BbGg and a bbgg insect mate and produce the following 480 offspring: Phenotype Number of Offspring Smooth, gray 119 Bumpy, white 117 Smooth, white 123 Bumpy, gray 121 What type of inheritance is displayed from these offspring
Answer:
Independent assortment
Explanation:
The type of inheritance displayed by the offspring is a simple independent assortment inheritance according to Mendelian law.
The result of crossing BbGg and bbgg is as follows (see the attached image)
4 BbGg smooth and gray
4 Bbgg smooth and white
4 bbGg bumpy and gray
4 bbgg bumpy and white
The phenotype ratio from the cross is 1:1:1:1 as far as the independent assortment is concerned.
Now, looking at the population of each phenotype from the cross
Smooth, gray 119
Smooth, white 123
Bumpy, gray 121
Bumpy, white 117
119:123:121:117 is approximately equal to 1:1:1:1.
Hence, the cross agrees with Mendel's law of independent assortment of genes.

Explain some of the reasons why not everyone shows traditional lateralization
Answer:
The right side of the brain may have developed more than the left side.Both sides of the brain developed equally.Explanation:
Lateralization is the term used to designate the tendency that some functions of the organism are more developed on one side of the brain. Traditional lateralization, promotes that these functions are more developed on the left side of the brain, making the right side of our body more dominant. However, it may happen that these functions develop more on the right side of the brain, or develop on both sides and in an egalitarian form, causing some people to have lateralization different from the traditional.
Which of the following statements about the fossil record is correct?
A. The fossil record includes more organisms that were abundant, or lived for long periods on Earth, than it is with those that lived for short periods of time and then became extinct.
B. The fossil record is richer with organisms that are the same ones as currently common and living on Earth today.
C. A fossil of a rain forest snake would not be found in an area on Earth that is currently a desert.
D. The fossil record is richer with organisms that resemble organisms that are those alive today.
Answer:
I believe the answer would be A
Explanation:
You would have more fossils of animals that lived longer time ago than recent one bc they would be more older and more beneath the ground.And for animals to fossilize takes a long time so more older animals would be fossils
Answer:
The answer would be option A.
Explanation:
The process of fossilization is a time taking process which undergoes several stages from drying and freezing to mineralization and petrification. A fossil takes about 2.5 to 3.5 billion years to form. Both biotic and abiotic factors plays an important role in fossil formation therefore, animals that were abundant and buried frequently are more likely to fossilize than animals that lived for a short duration. Moreover, animals that are more abundant and lived for a longer period of time would be likely buried beneath the earth and would have more chances of reaching an ideal condition for fossil formation such as no decomposition which could only be achieved in an oxygen deficit environment as oxygen accelerates the process of decomposition.For more information:

Which of the following describes how the pollen must travel in order for pollination to occur?
Question 11 options:
. from the stigma to the anther
from an anther to the style
from an anther to the stigma
from the stigma to the pollen tube
Answer:
ewan the anther to stigma pero dapat stamen to the stigma
Answer:
I believe the answer is "from an anther to the stigma"
Explanation:
Because to be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.

g One benefit of operons in bacteria is that they a. do not need ligands and regulatory proteins as single genes would. b. do not need any modification of the proteins after they are expressed. c. allow for alterations in DNA sequence by flipping promoters around. d. allow for coordinated gene expression of related genes on one mRNA controlled by one promoter. e. allow the bacteria to use a wide variety of carbon sources.
Answer:
d. allow for coordinated gene expression of related genes on one mRNA controlled by one promoter.
Explanation:
An operon is a group of functionally-related genes that share the same promoter region and the same operator which interacts with specific repressors or activators, and they are transcribed as a unit. This transcriptional unit (operon) is present in prokaryotic organisms (i.e., bacteria and archaea) but absent in eukaryotes. In an operon, each structural gene is known as a cistron, and they are transcribed together as a polycistronic primary messenger RNA (mRNA).
The excited electron then loses its energy as it travels down the
The excited electron then loses its energy as it travels down the Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light and fall back down to their original energy level.
What happens to an electron when it loses energy?
The lines in an emission spectrum occur when the electron loses energy, and "falls back", from a higher energy state to a lower one emitting photons at different frequencies for different energy transitions.
How can an electron in an atom lose energy?For an isolated atom or molecule in a gas, excited states of electrons often don't have any easy way to lose energy except by electromagnetic radiation- the light of some frequency. A little of the energy can go into internal vibrations for a molecule.

Porosity
Explanation:
I had another question like this and it was B so there u go
Meaning of soil porosity: Pore-spaces, also known as voids, are the area of the soil's volume that is not occupied by solids, either mineral or organic, hence option B is correct.
What is soil porosity?
Under field conditions, air and water are always present in the pore space. The amount of water that a specific volume of soil can hold depends on the amount of pore space.
How many pores, or holes, a soil has is referred to as its porosity. A proportion of the total volume of the soil material is used to measure a soil's porosity.
Soil particles are defined as those that are 2 mm in diameter or smaller and make up the inorganic component of soil. Sand, silt, and clay are the three types of soil particles.
Therefore, Porosity is a crucial indicator in locations where groundwater reserves supply drinking water.

a. No apoptosis
B. Ability to metastatize
C. Angiogenesis
D. Unregulated mitosis
E. Unmutated DNA
Answer:
i think it is c
Explanation:
The option that is not characteristics of cancer cells is E (Unmutated DNA).
Cancer is caused mutations or abnormal activation of cellular genes that control cell growth and cell mitosis.
The characteristics of cells that are cancerous include:
No apoptosis: Apoptosis is programmed death of a normal cell. This doesn't occur in cancer calls as the cells continue to divide giving rise to malignant cells.
Ability to metastatize: This is the ability of cancer cells to migrate to other normal cells and tissues of the body. This so because they are less adhesive to one another.
Angiogenesis: This is the ability of cancer cells to form new blood vessels that supplies blood to it for its nourishment.
Unregulated mitosis: This is the ability of cancer cells to grow without the usual cellular growth limits.
Mutation is the abnormal changes that occur in the deoxyribonucleic acid of a cell.
Cancer cell develop due to mutation of antioncogenes, which are genes present in cells which suppress the activation of oncogenes that lead to cancer.
Therefore, the option that is not a characteristics of cancer cells is E (Unmutated DNA).
