The pink rose has a type of protein for the petal shape on the other hand, the yellow rose has two types of protein for the petal shape feature.

Plant proteins also like other proteins, provide a variety of enzymatic, structural, and functional functions.

They also serve as storage media to suit the nutritional and development requirements of growing seedlings.

These can also responsible for coloration in plants.

Thus, as in the given scenario, the pink rose has a type of protein for the petal shape on the other hand, the yellow rose has two types of protein for the petal shape feature.

Answer:

Mixed cropping is also known as inter-cropping, polyculture, or co-cultivation. It is a type of agriculture that requires planting two or more plants simultaneously in the same field, interdigitating the plants so that they grow together.

Typically a mix of legumes and cereals or tuber crops is a common practice in marginal agro-ecological environments. The mixtures can be flexibly arranged to conditions such as late or early onset of the rainy season or status of soil fertility in different fields.

The cavity which separate or in between the nose and the mouth is the nasal cavity.

The nose and the mouth meet at a junction called the pharnx; option A

The nasal cavity refers to a large, air-filled space above and behind the nose in the middle of the face. It is the cavity which divides the nose and mouth.

However, the nasal septum divides the cavity into two cavities .

So therefore, the cavity which separate or in between the nose and the mouth is the nasal cavity.

Species adapte to their environment over time.

Answer:

see the file attached!!

The adapted plant would survive and reproduce, and others would die causing evolution.​ thus option C is correct.

Even though it has resulted in their distinctions, evolution is a biological phenomenon that affects all living things. The fossil record, comparative studies of structure and function, embryological development, and studies of DNA and RNA have all provided evidence to support the hypothesis of evolution.

Plant adapted themselves according to environmental conditions. In water scarcity conditions, plant changes their leaf structures in the thorns to reduce transpiration or stem become storage organ for water.

Because nonrenewable resources are diminishing in number, they will eventually become scarce, posing a variety of life dangers in the future.

Nonrenewable resources are defined as substances that are depleted faster than they can be replaced.

Renewable resources are abundant, and capturing them is a sign of new life on the horizon. It is necessary to decrease your reliance on nonrenewable resources. As we saw during the corona pandemic, most countries' economies are progressively deteriorating. It also has an impact on one's quality of life. As a result, it must be stated that the world population will decline in the twenty-second century.

Answer:

A.carbon dioxide

Explanation:

oxygen poor blood means the blood is rich with Carbon dioxide

The oxygen poor blood delivers to the lungs carbon dioxide out of the body organs and cells. Thus, the correct option is A.

The heart is divided into two separate pumping systems, which include the right side and the left side. The right side of the heart receives oxygen-poor blood that is deoxygenated blood from the veins and pumps it to the lungs, where the blood picks up oxygen gas from the alveoli and gets rid of carbon dioxide gas.

Deoxygenated blood has less oxygen or it is oxygen-poor and contains is carbon dioxide rich. The right heart pumps this deoxygenated blood to the lungs where it picks up additional oxygen gas.

As the blood travels through body, oxygen gas is used up, and the blood becomes oxygen poor or carbon dioxide rich. Oxygen-poor blood returns from the body to the heart by the superior vena cava and the inferior vena cava, the two main veins which bring blood back to the heart.

Therefore, the correct option is A.

Answer:

B. epiglottis

Explanation:

this is the part of your body that covers the windpipe when you swallow.

Answer:

a. Vascular

b. dermal

c. ground

d. dermal

Explanation:

Vascular is the bundle of phloem and xylem.

Dermal is epidermis, so for "b." it is upper epidermis and for "d." it is lower epidermis.

Ground provide structure.

The correct identification of leaf tissues of A, B, C and D are Vascular tissue, Dermal Tissue, Ground tissue and Dermal tissue respectively.

The specialized tissues that make up plant leaves are known as leaf tissue. Photosynthesis, gas exchange and transpiration in plants are mainly carried out by the leaves. Different types of cells perform different activities in leaf tissues.

The epidermis of the leaf, which covers both the upper and lower surfaces, is the outermost layer of tissue. Through tiny pores called stomata, it regulates water loss and acts as a protective barrier.

Between the upper and lower epidermis of the leaf is a layer of tissue called the mesophyll. It is in charge of most of the photosynthesis.

The movement of water, nutrients and carbohydrates throughout the leaf and throughout the plant is carried out by vascular tissues.

Guard cells: Special cells that surround and control the opening and closing of the stomata are found in the epidermis.

Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus. However, antiviral medications and vaccines are specific for viruses.

Options:

A prostaglandin

B protein hormone

C. peptide hormone

D. steroid hormone

Answer:

Amylin is peptidal harmone. Thus, the correct option is C.

Hormones are the chemical messengers of the body. They make their way through your bloodstream to tissues and organs. They have a long-term effect on a variety of processes, including growth and development.

Amylin is a peptide hormone produced in tandem with insulin by the pancreatic -cell and is hence lacking in diabetics. It works as a satiety agent by inhibiting glucagon secretion and delaying stomach emptying. As a result, amylin replacement could potentially improve glycemic control in some diabetics.

Amylin is a 37-amino-acid peptide hormone released by pancreatic beta-cells in response to a food stimulation together with insulin. It is inadequate in Type 1 diabetes patients and increased in Type 2 diabetes patients in the early stages, a disease marked by hyperinsulinemia.

Answer:

(a) stabilizing selection

Explanation:

Sickle-cell anaemia is a recessive disorder caused by the presence of two recessive alleles "s", so the genotype is "ss". This disorder is characterized by sickle haemoglobin. In an area with malaria, heterozygous individuals "Ss" (with one dominant allele and one recessive allele) have an advantage. These individuals will have both normal and sickle haemoglobin. But pathogen that causes malaria affects only normal haemoglobin, so heterozygous individuals will have half of the haemoglobin resistant to the pathogen and those individuals are resistant to malaria.

Stabilizing selection favours heterozygotes Ss,  disruptive selection favours dominant (SS) and recessive (ss) homozygotes, while directional selection favours dominant (SS) or recessive (ss) homozygotes. Since in this example, people with genotype Ss (heterozygotes) are at an advantage, then this is an example of stabilizing selection.

The level of sucrose solution will rise in the glass tube because water molecules will pass through the semipermeable membrane into the tube as water potential is higher outside than inside the tube.

Osmosis is the movement of water molecules from a region of low solute concentration or high water potential to a region of high solute concentration or low water potential through a semipermeable membrane until equilibrium concentration is attained.

The movement of water molecules is based on a concentration gradient, from a region where there are more water molecules to a region where there are fewer water molecules.

Fats and carbohydrates are the macromolecules that are energy sources. Fats are a better source of energy than carbohydrates as three fatty acid molecules have energy equivalent to 16 carbons.

Fats are the energy-providing macromolecule and are stored in the adipose tissue. They are made of fatty acids that are the source of the energy.

Fats contain the triglyceride molecule that produces fatty acids that produce the equivalent energy as the sixteen carbon molecules and hence are a more efficient source.
