Of the available options, the first one states that cellulose is a structural part of the hair, this is not correct for several reasons, first cellulose is a biopolymer characteristic of cellular walls in plants, and it's not present in animal cells, secondly human hair is formed mainly of keratin a protein, therefore their basic units are amino acids, not carbohydrates. Therefore taking this into consideration, the correct answer is option 1.

The hormone produced by cells around the embryo that maintains the corpus luteum and pregnancy is called human chorionic gonadotropin (hCG).

Human chorionic gonadotropin (hCG) is a hormone that is produced by cells around the embryo, that is, trophoblastic cells that develop into the placenta, after fertilization. Its main function is to maintain the corpus luteum during the early stages of pregnancy. The corpus luteum is a temporary endocrine structure that develops after the release of an egg from the ovary, that is, after ovulation. It produces progesterone, which is essential for the maintenance of pregnancy in humans.

If an egg is fertilized by a sperm, the resulting embryo secretes hCG, which signals the corpus luteum to continue producing progesterone. This is necessary to prevent the lining of the uterus from shedding and to maintain the pregnancy. If the corpus luteum did not receive this signal, it would degenerate after about 12 days, and progesterone levels would decline. This would cause the lining of the uterus to be shed and menstruation to occur. The levels of hCG in a woman's blood and urine can be used to diagnose pregnancy. hCG levels rise rapidly in the first few weeks of pregnancy and can be detected by a blood or urine test. After about 10 weeks of pregnancy, hCG levels start to decline and eventually level off.

All of these techniques are unique ways of choosing plants for breeding in an effort to enhance certain population traits, like height.  The first technique entails breeding with the entire population.

The second technique entails just choosing seeds from the population's higher plants. The third technique is choosing plants for breeding that are most similar to the population's mean height. The fourth technique is choosing five plants at random for breeding. The optimal strategy will rely on the precise objectives of the breeding programme because each method has benefits and drawbacks of its own. The term "population" describes the total number of members of a certain species residing in a given territory. It may also refer to the entire population of a certain demographic, such as an age or ethnic group.

Answer: 62.5 kilocalories

Explanation:

Otters are a subfamily of carnivorous mammals which consume a variety of animals such as amphibians, crustaceans, fish, snails, water insects, worms, birds, turtles, frogs and aquatic invertebrates (insects). They are great swimmers which helps them look for food, and they can close their nostrils being able to stay underwater for up to 4 minutes.

A calory is an unit of measurement of the energy found in food which is defined as the unit of thermal energy equivalent to the amount of heat needed to raise the temperature of 1 gram of water by 1 degree Celsius. For example, if a certain food provides 300 calories, this is the energy that the body could receive when consuming it.

To maintain its  weight, the female otter must consume 250 calories per kilogram of body weight per day. So if the otter has a weight of 25 kilograms, then 250*25= 6250 calories (or 62.5 kilocalories) needed per day to maintain the weight.

Limiting factors can be either abiotic or biotic. Examples: Abiotic → water, pH, radiation, salinity. Biotic → predation, competition, parasitism.

The ecosystem is composed of living and non-living elements that interact and depend on each other. These are the biotic and abiotic factors.

• Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements.

• Biotic factors are all the living components in the ecosystem.

Biotic and abiotic factors influence the survival and reproduction of living beings.

Limiting factors are environmental conditions that act directly on populations and individuals, limiting their distribution and growth.

These factors might be either biotic or abiotic and affect natality and mortality rate, migration, etcetera.

Limiting factors might be a result of the population density or might be dense-independent.

Carbohydrates, lipids, and proteins are the three primary macromolecules that compose living organisms . Additionally, proteins also contain nitrogen and, in some cases, sulfur. All three molecules are composed of carbon, hydrogen, and oxygen, but the ratios of each element differ.

Structural differences between carbohydrates, lipids, and proteins Carbohydrates: Carbohydrates are the body's primary source of energy. They are composed of carbon, hydrogen, and oxygen atoms. Carbohydrates are divided into three groups based on the number of monosaccharides that make up their molecular structure: monosaccharides, disaccharides, and polysaccharides.

The structural differences between the groups are due to variations in the number and arrangement of monosaccharides. Examples of carbohydrates in the body include glucose and glycogen.Proteins: Proteins are critical to many biological functions, including cell growth and repair. Proteins are made up of amino acids, and their primary structure is determined by the number and arrangement of these amino acids. The unique sequence of amino acids produces a three-dimensional structure, which determines the protein's function. Proteins can be broken down into two groups: fibrous and globular.

Fibrous proteins, such as collagen, are responsible for maintaining structural support in tissues. Globular proteins, such as enzymes, are involved in metabolic reactions. Examples of proteins in the body include enzymes, hemoglobin, and collagen.Lipids: Lipids are the most diverse of the three primary macromolecules. Lipids are not soluble in water, and they serve a variety of functions in the body, including energy storage, insulation, and protection. The structural differences between lipids are due to variations in the number and arrangement of fatty acids and glycerol. Fatty acids can be classified as saturated or unsaturated based on the number of double bonds between the carbon atoms. Saturated fats are solid at room temperature and are commonly found in animal products. Unsaturated fats are liquid at room temperature and are commonly found in plant products. Examples of lipids in the body include triglycerides and phospholipids.

In ventricular cardiomyocytes, drugs that inactivate the voltage-activated sodium (Na+) channels (SCN5A) can have several effects on cardiac function.

Here are some of the common effects:

Decreased depolarization: Voltage-activated Na+ channels are responsible for the rapid depolarization phase (phase 0) of the cardiac action potential in ventricular cardiomyocytes. Inactivation of these channels by drugs can slow down or inhibit the influx of Na+ ions, leading to a reduction in the rate and amplitude of depolarization.

Decreased conduction velocity: By inhibiting Na+ channels, the drugs can impair the conduction of electrical signals within the heart. This can result in a slowed conduction velocity through the ventricular tissue, leading to delays or blockages in the propagation of the electrical impulse.

Prolonged action potential duration: Inactivation of Na+ channels can impact the repolarization phase (phase 3) of the cardiac action potential. It can prolong the duration of the action potential, leading to a lengthening of the refractory period. This can have implications for the heart's ability to reset and initiate the next action potential.

The messenger RNA (mRNA) enters the free ribosome, and a polypeptide emerges.

The process of translation involves a large number of other molecules and macromolecules in addition to the mRNA template. Each component's composition may alter between species; for example, ribosomes may contain varying amounts of polypeptides and rRNAs depending on the organism. However, the overall designs and operations of the machinery responsible for protein synthesis in both bacterial and human cells are comparable. An mRNA template, ribosomes, tRNAs, and numerous enzyme components must all be present for translation to take place. Protein synthesis can be broken down into the same three processes as mRNA synthesis: initiation, elongation, and termination. Both prokaryotes and eukaryotes translate in a similar way. The process of translation in the prokaryote E. coli will be examined in this section, along with any distinctions between prokaryotic and eukaryotic translation.
