Answers
RuBP oxygenase-carboxylase (rubisco) is a key enzyme in photosynthesis. This enzyme can use carbon dioxide and oxygen as substrates.
→ During photosynthesis, in the first stage of the Calvin cycle, this enzyme incorporates carbon dioxide into the organic molecule ribulose 1,5 diphosphate forming a sugar molecule.
→During photorespiration, the enzyme attaches oxygen to its oxygenase reaction and produces two molecules, one three-carbon compound called 3-PGA, and another two-carbon compound called phosphoglycolate.
3-PGA can enter the Calvin cycle but phosphoglycolate cannot enter it, and thus two carbons are eliminated from it which leads to a decrease in sugar synthesis, making photosynthesis less efficient.
So, the statement in option A indicates the normal function of the rubisco during photosynthesis.
The correct option is B.

Which factors changed throughout the experiment? Check all that apply
Answers
In the experiment, two factors changed throughout the course of the study: the genes of the parental mice and the fur color of the offspring.
The genes of the parental mice: The experiment involved studying the genetic makeup of the parental mice, specifically focusing on the alleles responsible for fur color. The researchers likely examined the genes of the parental mice to determine which alleles they carried and how they could potentially be passed on to their offspring. By studying the genetic composition of the parental mice, the researchers could track the inheritance pattern of the fur color trait.
The fur color of the offspring: The primary objective of the experiment was to investigate how fur color is inherited in mice. To achieve this, the researchers likely observed and recorded the fur color of the offspring produced by the parental mice.
As the experiment progressed and new generations of mice were born, the researchers would have noticed changes in the fur color of the offspring. By comparing the fur color of the offspring to the known genetic makeup of the parental mice, they could analyze the inheritance patterns and determine whether specific alleles were dominant or recessive.

Explanation:
Explain five possible setbacks a company could face if they don't develop effective configuration management policies and processes.
Answers
Possible setbacks are the difficulty in keeping up with market changes, failures in product production, failures in product distribution, sector problems, problems in the management of employees.
We can arrive at this answer because:
The management of a company is essential for its proper functioning and the success of the production.One of the first problems that lack of management causes is the difficulty in keeping up with market changes. This makes the company outdated and inefficient.Talking about the production and distribution of the product harms sales and reduces the number of customers.Sectoral problems hinder organized production, which will also affect sales.Problems in managing employees will also be disadvantageous, as it will affect all of the company's compositional factors.Therefore, we can say that management is the most important point to be organized.

difference between mri and ct scan of abdomen
Answers
The biggest difference is that MRIs use radio waves and CT scan use X-rays.
Magnetic Resonance Imaging (MRI) is using radio waves and magnets, MRIs are used to view objects inside the body and commonly used to see brain organ. MRI scans produce a more detailed image of soft tissue, ligaments, or organs. Problems that may be easier to see with an MRI scan include soft tissue damage, torn ligaments, and herniated disks.
Computed Tomography (CT) Scan is a form of X-raying that involves a large X-ray machine. It usually are used to view bone fracture(s), finding internal bleeding or tumor(s) especially in abdomen. CT scans take a fast series of X-ray pictures, which are put together to create images of the area that was scanned.
CT scan is generally good for larger areas, while an MRI scan produces a better overall image of the tissue under examination. Both have risks but are relatively safe procedures.

Explain the following statement using evidence from the DNA sequences:
Mutations in the DNA change how proteins are made which leads to new and different forms of phenotypes.
Answers
A missense mutation is a Genetic alteration that causes the protein produced to encode a different amino acid at a specific location. Certain missense mutations change how the resulting protein functions.
Why do some changes in an organism's DNA sequence cause change, while others do not?While mutations always result in a change in the DNA sequence, they do not necessarily have a noticeable impact on the organism or alter the resulting protein. Since most amino acids can be encoded by two or more distinct codons, this is possible.
Can mutations be found using DNA sequencing?The ability to properly identify and characterise the majority of sequence changes makes direct DNA sequencing, in theory, the method for mutation identification with the highest degree of accuracy.

Hydrophilic substances "dissolve" in water, what does that mean?
How does it pull apart bonds like in glucose?
What about the lipid bilayer with the phospholipid hydrophilic head, why doesn't it get ripped off the tails?
Answers
Answer:
mark me pls
Explanation:
Q1)When a substance is said to “dissolve” in water, it means that it is able to mix with the water molecules and form a homogeneous solution. This means that the substance is evenly distributed throughout the water and is no longer visible as a separate entity. Hydrophilic substances are able to dissolve in water because they have a strong affinity for water molecules, allowing them to form strong hydrogen bonds with them.
Q3)The hydrophilic head of the phospholipid is held in place by a combination of electrostatic and hydrogen bonding interactions with the hydrophobic tails. These interactions are strong enough to keep the head and tail together, even when the bilayer is subjected to mechanical forces.
