Answer:
B. Because lions and tigers have many of the same genes.
Explanation:
You can rule out A, since all big cats and other predatory animals must hunt to survive.
C can be ruled out, as all animals have roughly the same cells.
D can be ruled out as well, since all animal cells have the same organelles (essentially the same reason C can be ruled out.)
That leaves us with option B. B is the most likely answer, as lions and tigers share most of their DNA with one another.

What is added as an anticoagulant to preserve blood specimens?
OA sodium citrate
B
sodium fluoride
O'c. potassium oxalate
OD liquid paraffin
E.
ethanol
Reset
Answer:
C. potassium oxalate for plato / edmentum
Explanation:
I took notes in the class and my notes say -
To prevent blood from clotting, toxicologists add anticoagulants to the blood sample. Anticoagulants such as potassium oxalate (30 mg/mL) is preferred over heparin or ethylenediaminetetraacetic acid (EDTA) because both heparin and EDTA interfere with the detection of certain chemicals, such as calcium, in the blood. If the blood is suspected of carbon monoxide poisoning, a layer of liquid paraffin is added over the blood sample. This layer prevents exposure to atmospheric oxygen.

A water body that flows on the surface of the earth is called a stream. The river is a larger water body compared to streams. Stream is shallow likened to river volume.
A stream that flows into two distinct rivers is part of two:
Option b. Tributary
This can be explained as:
A reservoir is a lake that reserves the water either created naturally or artificially.A stream that merges into the river is called tributary or affluent.A watershed is a drainage bay where the water from precipitation gets accumulated and drains to common river or water bodies.Therefore, a tributary is a stream that flows into two different rivers.

Negative pressure rooms are sometimes referred to as source isolation rooms, while positive pressure rooms are sometime called protective isolation rooms. Explain the thinking behind these names.
Answer:
Negative pressure rooms are sometimes referred to as source isolation rooms because they prevent potentially contaminated air to exit the room.
Positive pressure rooms are also known as protective isolation rooms because they prevent the entering of any pathogen in the air to the room where a patient with a compromised immune system is staying.
Explanation:
Negative pressure rooms or source isolation rooms have lower pressure than the outside. Due to this pressure difference, air can enter the place but can not leave it, trapping the pathogens. Patients with infectious conditions are in these rooms to prevent the spreading of the disease. That is why they are also called source isolation rooms. These rooms have a system that filtrates and circulates the air.
On the other hand, in positive pressure rooms, the air pressure is higher. As a result, the air, with any potential bacteria, virus, or particles, leaves the room to keep the patient safe. They are also known as protective isolation rooms because patients with a compromised immune system are there to protect them from any pathogens in the air.

Answer:
According to the cell cycle data provided in the table, these data indicate that cells spend most of their time preparing for the cell cycle (third option).
Explanation:
The cell cycle is divided into two major phases, interphase —without cell division— and cell division or mitosis. Interphase in turn is divided into three phases prior to the division process:
G1 phaseS phaseG2 phaseAssuming that the complete cell cycle lasts 24 hours, the cell will remain in interphase for 23 hours - preparing for the next division - investing only 1 hour in cell division or mitosis.
The data provided by the table indicate that, at a given time, there will be a greater number of cells in the interphase stages, indicating that cells spend most of their time preparing for the cell cycle.

Determine the parental genotypes and proportion of offspring genotypes for locus 2. What are the genotypes of the parents with respect to locus 2 (i.e., alleles B and b)
Answer and Explanation:
Alleles are the different varieties of genes. For every gene, somatic cells have two alleles.An allele that is not expressed by an organism might be passed to the offspring of The organism provides one allele.
It is difficult to conclude which two alleles of a gene exist within the chromosomes of organisms. that organism and can express in the next generation.
The parental genotypes can be determined by PUNNETT SQUARE, in which we use two letters to signify the genotype.
As the white throat code and the red throat code are alleles.
A lowercase letter represents the recessive form of a gene (allele), and a capital letter represents the dominant form of a gene (allele). For example, for the red-throated bird, white throat is a recessive trait, and red throat is a dominant trait.
There are basic steps of using Punnett Square. Step one is to determine the parent organism genotypes then write down “mating.” Draw a p- square. For each parent, split the letters of the genotype. Then place them outside the p-square. By filling the p-square, determine the genotype of the offspring. Then summarize results.

How might Kangaroo population suddenly increase? How might this affect the ecosystem?
Answer:
The kangaroo population could suddenly increase if the predator of the kangaroo found something else to hunt, or started to go extinct. If this were to happen, then the prey of the kangaroo would most likely go extinct due to the sudden rise in population of the kangaroo. If there were more kangaroo, then there would be less of whatever the kangaroo ate, then the prey of whatever the kangaroo ate would suddenly increase, it goes all the way down the chain.

either legally or spiritually, the community's farm, with the growers and consumers providing mutual support and sharing the risks and benefits
of food production."
-sustainable operation
-farmers' market
-farmers' cooperative
-CSA
Answer:
The correct answer is CSA.
Explanation:
Community Supported Agriculture (CSA) is an alternative model for the distribution of agricultural products directly from the farmer to the consumer, it consists of a group of people who form a cooperative to grow and consume food. Through this socio-economic model, consumers lend their support to producers, in exchange for a direct and regular delivery of biological products, that is, producers and consumers support each other and share the benefits and risks of food production.

Within a plant, photosynthesis is critical. It provides cells with the glucose they need for
energy. Photosynthesis is important for another reason, too. It's part of the flow of carbon
through organisms and the environment. This cycle, known as the carbon cycle, is essential
for life on Earth. It includes several processes that are occurring all the time. When plants
photosynthesize, carbon is removed from the atmosphere as carbon dioxide. When animals
and plants use cellular respiration, carbon is released into the atmosphere as carbon
dioxide. Organisms that die and are buried for millions of years turn into fossil fuels, which
are made of carbon. When humans burn those fossil fuels, carbon is released into the
atmosphere as carbon dioxide. Without enough carbon dioxide in the atmosphere, the
planet would be too cold. But too much carbon dioxide contributes to the warming of the
planet that could make it too hot to survive.
Based on the passage, what is one reason that the carbon cycle important?
A It adds carbon into the atmosphere whenever the level begins to drop too low.
B
It helps maintain a level of carbon in the atmosphere that is neither too hot nor
too cold.
с
It removes carbon from the atmosphere whenever the level begins to become
too high.
D
It releases carbon into space, preventing it from building up in Earth's
atmosphere.
