When a cell is actively growing, the arg operon is _____, and arginine is _____.
Answer:
The correct answer is - on, actively synthesize.
Explanation:
The arg operon is a negative regulator that releases or regulates the production of arginine in only the presence of arginine. Attaching the arginine to the arginine repressor protein causes the repressor to bind to the operator sequence.
When a cell is growing actively this operon is on and the synthesis of arginine in this cell is continuous. Arginine induces a conformational change in the protein structure.
Which of the following is most consistent with the modern theory of evolution?
Parents pass their physical trait to their offspring those offspring with traits that help them survive in the environment are able to reproduce.
Parents change their physical traits in order to survive in the environment, then those parental traits are passed to their offspring
Life on this planet came from another planet far out in space
Living organisms have not changed for hundreds of millions of years,
Answer:
The correct answer is Parents pass their physical traits to their offspring; those offspring with traits that help them survive in their environment are able to reproduce.

5) The following picture is of a single organism that has been Gram stained and is viewed under oil immersion on the compound light microscope. What is the reason for a single organism appearing like this after being Gram stained
Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.

Can someone explain what this text means?
Encasing the cell is a membrane with special gates, channels and pumps that let in or
force out selected molecules.
Answer:
The text is explaining a cell membrane.
Explanation:
A cell membrane is made up of a phospholipid bilayer that acts as a kind of "skin" for the cell. The membrane helps the cell maintain homeostasis and filter out harmful particles. Elements like oxygen are allowed to pass through via protein channels, which act as gates. Does this answer your question?

Explanation:
A genomic researcher is analyzing the genome of different species of raptors. She finds that a particular sequence in the Bald Eagle genome is identical to a sequence found in the Red Tailed Hawk, while most other sequences in those two genomes differ at many nucleotides. (The most recent common ancestor between Bald Eagles and Red Tailed Hawks was approximately 6.8 million years ago, which is plenty of time for mutation to generate DNA sequence variation.) Which of the following could explain the identical sequence in these otherwise differing genomes?
a. The sequence encodes a protein critical for the production of feather color.
b. The sequence encodes a gene that is critical for life and cannot be easily mutated while retaining function.
c. The sequence is from an intron of a gene that encodes a protein in connective tissue.
d. None of these
Answer:
d. None of these
Explanation:
Probably the identical sequence found in both species is an ultraconserved sequence.
An ultraconserved element is a particular DNI sequence that remains exactly the same through evolution, with almost no modification, and that is shared by at least two completely different species.
These ultraconserved DNI portions seem to be highly essential for life. However, their function could not be determined yet. Most of them do not codify for proteins, but they could play a significant role in gene regulation.
It is suggested that these sequences are so significant for life that only a small change would compromise the organism´s aptitude.
The statement 'the sequence encodes a gene that is critical for life and cannot be easily mutated while retaining function' could explain the identical sequences (Option B).
What is sequence homo-logy?The term sequence homo-logy makes reference to the similarity between nucleotide sequences due to a common origin.
If a sequence is identical between two or more species, then it exhibits a 100% sequence homo-logy.Sequence homo-logy enables the determination of the level of functional conservation in a given gene.In conclusion, the statement 'the sequence encodes a gene that is critical for life and cannot be easily mutated while retaining function' could explain the identical sequences (Option B).

Which statement describes a relationship that is an example of mutualism?
A. Remoras attach to and eat food on a sea turtle.
B. Ticks live on and drink blood from livestock.
C. Bees drink nectar from and pollinate flowering plants.
D. Rabbits live in and eat vegetables from garden plants.
Answer:
C. Bees drink nectar from and pollinate flowering plants.
Explanation:
Ecology can be defined as the scientific study of the relationship between living organisms such as plants and animals in relation to their physical and biological environment.
In Ecology, mutualism can be defined as an symbiotic relationship or interaction between two or more living organisms of different species that typically involves each organism benefiting positively. Therefore, mutualism influences the survival and reproduction of living organisms in their habitats.
Hence, the statement which describes a relationship that is an example of mutualism is bees drink nectar from and pollinate flowering plants. The flowering plants serve as a source of nectar for bees to feed on while the bees engage in the pollination of the flowering plants, suggesting a mutual benefit (mutualism) between the two species.
Pollination can be defined as a process which typically involves the transfer of a pollen grain from the male part (anther) of a plant to a ovule, stigma, or flower of a female plant, in order to stimulate fertilization and production of seeds. Also, this transfer of a pollen grain (male gametophyte) is often effected by bats, wind, birds and insects such as bees.

Describe how the pH and hydronium ion concentration will change in a solution as an acid is added to it.
Answer:
If the hydronium concentration increases, the pH decreases, causing the solution to become more acidic. This happens when an acid is introduced. As H+ ions dissociate from the acid and bond with water, they form hydronium ions, thus increasing the hydronium concentration of the solution.

12. How much energy is stored when a mass of 70kg is lifted upto
the height of 30m?
Answer:
E = 20580 J
Explanation:
Given that,
Mass of the object, m = 70 kg
It is lifted upto the height of 30 m
We need to find the energy stored when the mass is lifted. We know that, the energy stored by the object is given by :
E = mgh
Put all the values,
E = 70 kg × 9.8 m/s² × 30 m
E = 20580 J
So, 20580 J of energy is stored in the object.
plant reproduction requires the presence of auxins, as well as a large amount of sugar for energy. which two main plant tissues work together to release sugar and carry hormones so that reproduction can take place?
Answer:
The two main plant tissue that works together to release sugar and carry hormones so that reproduction can take place are: The ground and the vascular tissue.
Explanation:
The two main plant tissues that work together to release sugar and carry hormones so that reproduction can take place are Xylem and phloem.
What do you mean by Hormones?Hormones may be defined as a chemical delivered by endocrine glands and discharged into the blood and fascinated to a distantly located target organ.
Xylem is responsible for the transportation of water from the ground to the stem via roots, while phloem, the vascular tissue responsible for the transportation of dissolved sugar from the leaves to the other parts of the plants.
