Many plants that grow on land store energy in the form of starch. When the plants need energy, the molecules of starch can be broken down into monosaccharides. What type of biomolecule is starch? *
A .Protein
B. Carbohydrate
C. Lipid
D. Enzyme
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.

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).

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.

Why is there an increase in the number of people infected with the disease despite the increase in the number of vaccinated?
Answer:
Some people refuse to take the vaccine. a person who carries or has the virus can infect hundreds of people. Therefore the few people who don't take vaccines give it to others. Also, people with the vaccine can still get corona. Most people have stopped wearing masks once they get the vaccine so they are at high risk too.
Explanation:
Basically, people's ignorance and lack of understanding are causing this.

Give an explanation as to why there is little organic matter in rain forest soil and what would happen to the

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.

Proteins are one of four classes of biological macromolecules. Which of the following statements regarding proteins is NOT true?
A. Amino acids are the monomers of proteins.
B. Proteins contain nitrogen as well as carbon, hydrogen, and oxygen.
C. Proteins have only one specific function- to regulate the rate of biochemical reactions.
D. Protein monomers have a carboxyl group on one end and an amino group on the other.
Answer:
Statement 'C' is incorrect
Explanation:
Enzymes (which are a form of proteins) have a function of regulating the rate of biochemical reactions (they're biological catalysts, meaning they speed up reactions) ₋ in this instance, the statement would be correct.
However, this is not the only, or as the statement puts 'one specific function' of an protein. For example, haemoglobin (a protein) contains haem groups that bind to oxygen. In this instance, a protein's function has nothing to do with 'biochemical reactions'.
Hope that helps! x
Proteins having only one specific function which is to regulate the rate of
biochemical reactions is False.
Proteins are compounds which contain elements such as Nitrogen, Carbon,
Hydrogen and Oxygen. They act as the building block of life as they are
needed to replace worn-out tissues, supporting tissues and for growth
processes which is different from the function of regulation of biochemical
reactions.
Protein is formed as a result of the combination of two or more amino acids
which have carboxyl and amino groups present on different ends. Protein
have various functions such as supporting tissues.

If humans have altered the natural environment, describe the changes made by humans and their impact on the species.
Answer: The changes that humans have made are the changes to the atmosphere. That is the most significant change. The burning of fossil fuels increases the Co2 levels in the atmosphere along with other greenhouse gases such as methane. This causes the temperature to rise because the heat waves are stuck in the layer. The PH levels continue to rise in the oceans due to climate change also.

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.

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
