Answer:
They can determine if a trait is recessive or dominant, which means in can determine what will show up in the offspring.
A female, tortoise-shell, tailless Manx cat mates with a male solid black tailless Manx cat. Their first litter produced 1 tailless tortoise-shell female, 1 tailless black female, 1 tailed black female, 1 tailless orange male, 1 tailless black male and 1 tailed orange male. In the second litter, they had 1 tailed tortoise-shell female, 2 tailless black females, 1 tailless black male, 1 tailless orange male, and 1 tailed black male. (Hint: Look at each trait separately for phenotypic ratios, Mendelian vs NonMendelian patterns)
Required:
a. What are the inheritance patterns of the two genes described?
b. What are the genotypes of the parents?
A)
It is possible to obseve that the fur color of the feline is connected with the male chromosome "X". The presence of Xb (recessive) and XB (dominant) results in the tortoise color.
The ausent tail T is carried in the autosomes with a dominacy over the presence of tail "t" and the presence of both dominances "TT" results in the death of the offspring.
B) Genotypes of the parents:
Male: XbY, Tt
Female: XBXb, Tt
how do muscle cells produce energy through aerobic and anaerobic respiration
Answer:
Cellular respiration is the process by which cells make ATP by breaking down organic compounds from food. Muscle cells are able to produce ATP with oxygen, which is called aerobic respiration, or without oxygen, an anaerobic process called anaerobic glycolysis or fermentation.

what do all vertebrates and invertebrates have in common?
A. They are prokaryotic.
B. They are covered by an outer skeleton.
C. They are multicellular.
D. They are bilaterally symmetrical.
Answer:
C.
Explanation:
All invertebrates are animals, and all animals are multicellular, so all inverteberates are multicellular. They are not prokaryotic because all animals have eukaryotic cells, like humans. They are also not all covered by an outer skeleton like worms for instance. They are also not all bilaterally symmetrical. One animal that is not bilaterally symmetrical is the fiddler crab.

Give an explanation as to why there is little organic matter in rain forest soil and what would happen to the
material after deforestation.
It is due to faster decaying of dead plants and recycling of nutrients by the new plants.
Why there is little organic matter in rain forest soil?The soil of rain forest soil contains less organic matter than other forest soils because the warm humid conditions encourage faster decaying of dead plants and recycling of nutrients by the new plants.
So we can conclude that faster decaying of dead plants and recycling of nutrients by the new plants is the reason for low content of organic matter.

The boy was deemed an appropriate candidate for surgery at this time, with a second surgery planned during his teen years to complete the correction. The boy was adopted, and no family history was available. He had no personal history of excessive bleeding or bruising. The pre-surgical CBC results including platelet count were within reference ranges. Pre-surgical hemostasis testing is as follows: Ryan L.

Answer: The PT and APTT are valuable blood clotting time determination principles.
Explanation:
The principle of PT or prothrombin test determines the time required for the clot formation when additional calcium factor is added.
The principle of APTT or activated partial thromboplastin time is a test which determines the time required for the formation of the blood clot after the adding the calcium and phospholipid factors. This process activates the different blood clotting factors in the blood responsible for clotting of blood.

When we mix the two with the hot water below, the hot water rises to the top, mixing with the cold water to form purple water.
What are water molecules?A water molecule is described as a molecule consisting of two hydrogen atoms bound to an oxygen atom, and its overall structure is bent, because the oxygen atom, in addition to forming bonds with the hydrogen atoms, forms two pairs of non-bonding atoms, which also carries shared electrons.
For the above given information, when we heat water, the water molecules move more quickly which travels farther and farther, bouncing off each other.
A volume of hot water contains fewer molecules and weighs slightly less than a volume of cold water because there is more space between the molecules resulting in hot water having a lower density than cold water. When we mix the two with the hot water below, the hot water rises to the top, mixing with the cold water to form purple water.
Thus, when we mix the two with the hot water below, the hot water rises to the top, mixing with the cold water to form purple water.

Wildlife can be scarce in many large, densely populated cities. A few plants and animals can be found in theseareas. For example, rats, mice, pigeons, cockroaches, and other insects are common in cities. Trees can grow by sidewalks or in local parks. Some cities even have small populations of coyotes within city limits.
Do you think these cities meet the definition of an ecosystem? Explain your reasoning.
Answer:
Yes
Explanation:
Considering that other lifeforms, more than one species, is able to live in those cities, mean that its abiotic factors can sustain life. An ecosystem is a community with biotic (living organisms) and abiotic factors (environment).

a. It produces glucose, which provides energy for the cell.
b. It produces carbon dioxide, which combines with hydrogen to form sugar
c. It produces ATP, which stores energy that is used by the cell.
d. It produces oxygen, which combines with hydrogen to prevent cell poisoning.
Answer:
I think b.
Explanation:
Cellular respiration uses glucose and oxygen to form co2.
It produces glucose, which provides energy for the cell.
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.What is cellular respiration?It is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.There are four stages:- glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation.To know more about cellular respiration here

Starch is a type of carbohydrate.
What do you mean by carbohydrates?A carbohydrate is a biomolecule consisting of carbon, hydrogen and oxygen atoms, usually with a hydrogen–oxygen atom ratio of 2:1 and thus with the empirical formula Cₘₙ.
Carbohydrates are found in a wide array of both healthy and unhealthy foods—bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and cherry pie. They also come in a variety of forms.
The healthiest sources of carbohydrates—unprocessed or minimally processed whole grains, vegetables, fruits and beans—promote good health by delivering vitamins.
