Which cell technology was made possible by the development of micromanipulation tools
One of the cell technologies that was made possible by micromanipulation tools is reproductive cloning.
Reproductive cloning is a form of artificial reproduction using the cloning technique. It is distinguished from therapeutic cloning or, more properly, cloning for therapeutic purposes.
There are two cloning methods that could be considered for human reproduction: cloning by cleavage of a blastocyst, and cloning by transfer of a cell nucleus into an enucleated ovum.
Domain is a newer portion of the classification system that includes Eukarya and Prokarya. What information most likely dictated that this new level be created? New data about the geographic location of organisms New data about evolutionary relationship between organisms New data about the behavior and interactions of organisms in the wild New data about the physical appearance of organisms
B is the right answer for e2020
New data about evolutionary relationship between organisms
Explanation;Classification involves grouping based on their similarities and differences. The most useful way of classifying organisms is by use of evolutionary relationships which results to an organized classification of organisms.Knowledge on evolutionary relationships about different organisms has greatly changed over time and therefore relationship among organisms, grouping of organisms has continually been revised as a result of availability of new information concerning organisms.Therefore, it is this new data or information about evolutionary relationships among organisms that prompted revision and it was seen necessary to add a level in the hierarchy of classification.What causes the Moon to orbit around the Earth?

list three substances that need to be transported into all kinds of animal cells in order for them to survive
Animal cells require oxygen for cellular respiration, glucose for energy, and amino acids for protein synthesis. These essential substances must be transported into cells to maintain cellular functions and ensure the survival of the cell.
Explanation:Three substances that need to be transported into all kinds of animal cells for them to survive are oxygen, glucose, and amino acids.
Oxygen is crucial for the process of cellular respiration, where it is used to help convert glucose into adenosine triphosphate (ATP), which is the energy currency of the cell. Glucose is a simple sugar that serves as a primary energy source for cells. Lastly, amino acids are the building blocks of proteins and are essential for constructing cellular structures and facilitating various metabolic functions.
Without these key substances, animal cells cannot perform necessary functions such as energy production, building and repairing tissues, and maintaining homeostasis. Animal cells have specific mechanisms, including active transport and facilitated diffusion, to ensure the proper intake of these molecules.

Which of these activities are ways people degrade commons? Select the two correct responses.
A. Farmers allow livestock to overgraze federal pastureland.
B. Rangers limit the number of visitors to a nature preserve.
C. Rangers allow native plants to grow unchecked in a park.
D. Hunters hunt a valued species to extinction.
E. Politicians protect the habitat of an endangered species.
The correct answer is option , A and D
Here, the word common refers to the “Earth” and “its precious resource”. If a farmer allows overgrazing of pastureland, the land gets exposed to extreme weather condition and thus easily get eroded which could even lead to desertification. Also when a hunter kills a valued species that is at the verge of extinction, the ecosystem gets disturbed as the connecting link gets extinct which also disturbs the food chains and stability of the natural food web.
There are different kinds of agricultural activities. The activities that are ways people degrade commons are;
Farmers allow livestock to overgraze federal pastureland. Hunters hunt a valued species to extinction.What happens when one allow livestock to overgraze an area?In course of overgrazing, animals are known to limit or reduce the plant leaf areas, and thus it lowers plants' ability to trap sunlight and grow new set of leaf material.
This brings about a reduction and so there is slows down of plant regrowth and this can lead to the death of the plant.

Why do you think so many dogs die from bloat? what factors influence the mortality rate of this disease?
Answer:
Many dogs die from swelling because they need medical attention as soon as possible and their owners cannot reach the vet in less than 30 minutes. These dogs will need surgery, but surgery does not always work, which influences the high mortality rate of this disease.
Explanation:
Abdominal bloating is a condition characterized by abnormal fluid accumulation in the cavity of the dog's abdomen. This disease, when not treated quickly, can progress to something more severe and pressure the diaphragm, causing difficulty breathing. But what is really worrying is the disorder that is causing this signal, since the accumulated fluid in the abdominal cavity can come from the internal organs, blood vessels or lymph nodes.
Abdominal bloating is a disease that has a high mortality rate in dogs, because the animal needs veterinary care as soon as possible and most dog owners cannot reach the vet in less than 30 minutes. In addition, the dog will need surgery, however, surgery does not guarantee that the swelling will resolve and the animal will still be at risk of death.

Suppose that goats have one gene that codes for color, where a is brown and a is white. the goats also have another gene that codes for height, where b is tall and b is short. if these two genes are unlinked, what is the probability that a cross between aa bb × aa bb parents will produce two out of six offspring that are brown and short? enter your answer as a decimal, rather than as a percentage.
The probability that a cross between aa bb imes aa bb parents will produce two out of six offspring that are brown and short is 0.0156.
In order to solve for the probability of obtaining a specific number of offspring with certain traits, we need to use the binomial probability formula. Since the traits are unlinked, the probability of an offspring being brown (aa) and short (bb) is the product of their separate probabilities. The probability of an offspring being brown (aa) is rac{1}{4}, as both parents are aa, and the offspring must inherit an a allele from each parent. Similarly, the probability of an offspring being short (bb) is also rac{1}{4}. Thus, the individual probability for an offspring to be both brown and short is (rac{1}{4}) imes (rac{1}{4}) = rac{1}{16}. To find out the probability of having exactly two such offspring out of six, we apply the binomial probability formula inom{n}{k}p^k(1-p)^{n-k}, where n is the total number of offspring (6), k is the desired number of offspring with the traits (2), p is the probability of one offspring having the traits (rac{1}{16}), and 1-p is the probability of one offspring not having the traits (rac{15}{16}). Plugging in the values we get inom{6}{2}(rac{1}{16})^2(rac{15}{16})^4, which calculates to 0.0156.

Which is moved by transport proteins? please help
water
carbon dioxide
oxygen
calcium
Calcium is moved by transport proteins across cell membranes, while water, carbon dioxide, and oxygen can pass freely without such assistance.
Among water, carbon dioxide, oxygen, and calcium, calcium is the molecule that is moved by transport proteins across cell membranes. Water, carbon dioxide (CO2), and oxygen (O2) can move freely through cell membranes due to their small size and the nature of the lipid bilayer. However, calcium ions, which are charged particles, cannot easily pass through the plasma membrane without assistance. They require specific carrier proteins to facilitate their movement, often in a process that involves changes in the shape of the transport protein. This can be a passive process, as in facilitated diffusion, or an active process that requires energy, commonly in the form of ATP or an existing gradient of other ions or molecules.

Collaboration with other researchersPublish available research findings to build your network2) Change the size and scope ant time frame of the research
The scientist can work around the given limitations using the above two ways due to the following reason:
Source for more funding;
a) Collaboration and networking with other researchers
A researcher who is met with limited resources to complete a study can
collaborate with other researchers and build networks, to share both
resources, skills and ideas that are geared towards completing the study.
Such collaboration will reduce the amount of duplicated work within the
scientific community and increases the information flow, such that the
researcher can be involved in a new research and also be granted access
to a new funding source
b) Publishing current findings and discoveries
Highly productive researchers are known to be able to publish several
findings within a limited research grant and also they are known to attract
more grant. Therefore, it is important to publish any new findings that have
been made such that it will create awareness among members of the
scientific community and build up network with which to connect with
stakeholders such as gatekeepers within scientific networks and also
becoming more involved which can bring knowledge and attract funding
2) The researcher can scale down the study to reduce cost by reducing the
level to which the research was originally planned:
Cost savings can be made by changing the research direction and
methodologies, through the use of innovative alternatives that provide
similar results
The timing for the study can be reduced to reduce certain time based
expenses, or increased to the costs due to paying for services which are
