Explanation:
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).

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.
How do limited abiotic resources impact the overall biotic organisms in an ecosystem?
Answer: Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight. ... Limiting factors keep populations within an ecosystem at a certain level. They may also limit the types of organisms that inhabit that ecosystem.
Explanation:
All of the following are characteristics of cancer cells except
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).

leaves of cactus are modified into thorns
Answer:
To reduce loss of water through transpiration leaves of cactus plants are modified into spines.
Explanation:
Answer:
leaves are reduced to spines in a cactus , so that the water does not get evaporated with the heat of the SUN. 1. They are present in hot deserts which are scarce in water so in order to reduce the loss of water by Transpiration from the surface of the leaves, its leaves are reduced to spines
Claim: Warmer weather caused Galetown to have more severe storms.
can you explain why this happens please?
Answer:
Warmer weather caused Galetown to have more severe rainstorms. When the temperature of an air parcel starts out higher, it will have to rise higher in the troposphere before the temperature of the air parcel and the surrounding air are equal. When the temperatures become equal the air parcel will stop rising.
Explanation:
Answer: When the temperature of an air parcel starts out higher, it will have to rise higher in the troposphere before the temperature of the air parcel and the surrounding air are equal. When the temperatures become equal the air parcel will stop rising.

This picture shows different amounts of space in between the particles of two
different soil samples.
Which word best describes what we are seeing?
Answer:
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.

explain the advantage of the synaptic cleft being so small
Answer:
The size of the synaptic cleft is small which results in the neurotransmitters to pile up over time thus making the neurotransmitters' concentration increase and therefore can proceed with their function of sending nerve impulses. Hope that helped!

The pH scale ranges from ____________ to ____________ and is used to indicate the ____________ of a solution.
Answer:
Acidic, Basic, acidity
Explanation:
The PH scale ranges from acidic to basic and is used to indicate the acidity/alkalinity of a solution.
A normal PH scale ranges from the number 0 to 14. When the PH of a solution ranges from 0 to 7 is said to contains acidic contents in it. If the solution is greater than 7, it is said to be alkaline and when the solution is average(7) it is said to be neutral solution.
Example of an acidic substance/solution is lemon juice, solution that contain alkaline is bleach.

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.
The user needs to drag the slider bar in an upwards direction in order to completely melt away a body layer when in the dissection study area.
True or False
Answer:
False
Explanation:
During the dissection study the body is kept in laying position so that the scientist can easily perform experiments. The body is kept in laying position not in upward position. The body in upward position will have gravitational effect on the fluids and the body layer will not melt.

Answer:
viruses are not fit into broadest taxanomic system because:
they are not cells
they do not reproduce their own
they do not respond to stimuli.
