Answer:

Parenchyma

Parenchyma is a tissue composed of polyhedral living cells having thin walls and is concerned with vegetative activities of the plant. The individual cells of the tissue are called parenchyma cells.

Types of parenchyma:

Assimilatory: parenchyma cells which take part in photosynthesis contain chloroplasts and form a tissue called Chlorenchyma. These cells have a single or many vacuoles.

Storage Parenchyma: Some parenchyma cells contain leucoplasts. Parenchyma cells may store reserve materials. Amides, proteins and sugars are found dissolved in cell sap, as in roots of sugar-beet. Starch, proteins and fats occur in cytoplasm in the form of small particles. Proteins, starch grains and oils are found in the endosperm and cotyledons of many plants. In succulent plants, parenchyma cells which store water are present. Such cells are large, thin-walled and have only a thin layer of cytoplasm.

Aerenchyma: The tissues with prominent intercellular spaces is called Aerenchyma, e.g., occurring in plants growing in waterlogged soils and aquatic environments.

Pseudo-parenchyma: These are thin walled and elastic and meristematic in nature.

Chromoplast Parenchyma: Chromoplast contain pigments and is common in petals of flowers, fruits etc.

Origin:

Parenchyma tissue of the primary plant body, i.e., parenchyma of the cortex and the pith, of mesophyll of leaves and of flower parts, differentiates from the ground meristem. The parenchyma associated with the primary and secondary xylem is formed from pro-cambium and the vascular cambium. Parenchyma also rise from the phellogen in the form of phelloderm.

Functions Of Parenchyma Tissues

In plant’s body or in its organs, the cell wall parenchyma appears as ground substance in which other tissues such as vascular tissues are embedded.

The apical meristems and the reproductive cells are parenchymatous. These are also involved in the phenomenon of wound healing and regeneration.

The parenchyma is also precursor of the other tissues. The parenchyma cells bring about the functions of photosynthesis, assimilation, respiration, storage, secretion, excretion, etc., as they have living protoplast.

The parenchyma cells associated with xylem and phloem are connected with transportation of food and water.

The intercellular larger portions of plants, such as pith, all or most, of the cortex of the root and shoot, the pericycle, the mesophyll of the leaf, and the fleshy parts of the root and shoot, the pericycle, the mesophyll of the leaf and the fleshy parts of the fruit consist of parenchyma cells. They are also present in xylem and phloem.

Explanation:

If 46% of the loci in a population are heterozygous, then the average homozygosity in the population would be 54%. So the correct answer is 54%.

To calculate the average homozygosity in the population, we need to first determine the percentage of loci that are homozygous. Since we know that 46% of the loci are heterozygous, we can subtract this from 100% to get the percentage of loci that are homozygous:

100% - 46% = 54%

Based on the information provided, if 46% of the loci in a population are heterozygous, then the remaining loci must be homozygous. Therefore, the average homozygosity in the population would be 100% - 46% = 54%. So the correct answer is 54%.

Answer:

Explanation:

The four elements been referred to here are hydrogen, oxygen, carbon and nitrogen.

These four elements constitute the majority of the human body because of a combination of factors. Although, some of these factors are the major reasons, for instance the human body is made up of cells which are the basic structures of life. The cell consists of over 70% of water (which is made of hydrogen and oxygen). Also, oxygen is inhaled through the process of respiration which combines with other molecules (such as haemoglobin to form oxyhaemoglobin) in the human body. These among others make oxygen the most abundant element in the human body.

Naturally occurring organisms usually have a high concentration of organic molecules (molecules made of majorly carbon and hydrogen). This makes the human body have a high percentage (after oxygen) of carbon and hydrogen. Also, carbohydrates (which are later converted to glucose) form a large part of our diet and are stored in the body as glycogen (causing the body to have a high amount of carbon and hydrogen atoms).

Nitrogen is an essential part/element found in amino acids which are building blocks of protein. Proteins are involved in several metabolic activities in the body; this makes the abundance of nitrogen the fourth (one of the four) most common element in the body. It should be noted that amino acids also have carbon and hydrogen elements also.

The combination of the factors above among some other factors make the human body comprise mainly of these four elements

Living organisms like animals and plants are primarily made up of carbon, nitrogen, oxygen, and hydrogen.

Humans are primarily composed of four elements hydrogen, oxygen, carbon, and nitrogen.

The four elements that are primarily found in the human body play a crucial role in the developmental, physiological, and chemical processes of the body.

The human body is made up of cells, which constitute these elements and are 70% water. Oxygen is vital for the respiration process, in which complex substances are broken down to yield energy.

Carbon and hydrogen are organic molecules that make up the essential nutrients of the body such as carbohydrates and proteins.

Thus, the combination of these elements is required for the development and survival of organisms.

Answer: The digestive system is responsible for breaking down food and absorbing nutrients from it, while the respiratory system is responsible for bringing oxygen into the body and removing carbon dioxide.

Explanation:

The digestive system consists of a number of organs that work together to process food and extract nutrients from it. These organs include the mouth, esophagus, stomach, small intestine, large intestine, and rectum. The digestive system starts with the mouth, where food is mechanically broken down by chewing and mixed with saliva, which contains enzymes that begin the process of breaking down food. The food is then swallowed and passes through the esophagus, which moves it to the stomach, where it is mixed with stomach acid and enzymes that continue the process of breaking down the food. The partially digested food is then moved to the small intestine, where it is further broken down and the nutrients are absorbed into the bloodstream. The remaining indigestible material is moved to the large intestine, where water is absorbed and the material is eliminated through the rectum.

The respiratory system consists of the nose, mouth, pharynx, larynx, trachea, bronchi, and lungs. When we inhale, air passes through the nose or mouth, down the pharynx and larynx, and into the trachea. The trachea then splits into two bronchi, which lead to the left and right lungs. The lungs are made up of tiny air sacs called alveoli, where oxygen from the air we inhale is exchanged with carbon dioxide from the body's cells. The oxygen-rich blood is then carried back to the heart, where it is pumped to the rest of the body. When we exhale, the carbon dioxide is expelled from the body.

Explanation:

The photosynthetic reaction involves the reactants carbon dioxide, light energy, and water.

Photosynthetic is the process through which plants turn carbon dioxide, water, and sunlight into oxygen and sugar-based energy.

The most typical abbreviation for photosynthesis is 6CO2 + 6H2O → C6H12O6 + 6O2.

This suggests that the transformation of the reactants—six carbon dioxide molecules and six water molecules—into the products—a sugar molecule and six oxygen molecules—takes place as a result of chlorophyll's absorption of light energy (implied by the arrow).

The photosynthetic cycle contains three stages, which are as follows: Light energy is absorbed by chlorophyll, which then divides water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. Carbon dioxide is reduced, which results in the creation of carbohydrates.

Explanation:

The possible cause of Emily's dying crops, indicated by white spots and cracked ground, could be salinization.

Salinization refers to the accumulation of salt in the soil, which can have detrimental effects on plant growth and health. When the soil becomes salinized, it means that the salt concentration in the soil is too high for plants to tolerate. The white spots observed on the ground could be salt deposits left behind as the water evaporates, indicating the presence of excessive salt.

Salt accumulation in the soil can occur due to various factors, such as irrigation practices with high-salt water or poor drainage that leads to the accumulation of salts from groundwater. As the salt concentration increases, it creates an osmotic imbalance that affects the ability of plants to take up water, leading to dehydration and wilting. Additionally, high salt levels can directly damage plant tissues and interfere with essential physiological processes.

If Emily's crops are experiencing wilting, white spots, and cracked ground, it suggests that salinization is a likely cause. Proper soil management practices, such as improving drainage, leaching salts, and using appropriate irrigation methods, can help mitigate salinization and restore the health of the crops.

In a cross section of a peripheral nerve, the axon with the lowest longitudinal resistance would be the one with the largest diameter and the most extensive myelination.

Larger diameter axons have a lower longitudinal resistance due to their increased surface area, which allows for more efficient signal transmission. Myelination also plays a crucial role in reducing resistance, as it insulates the axon and increases the speed of signal propagation through saltatory conduction. Myelinated axons exhibit lower resistance compared to unmyelinated axons of the same diameter.

In summary, the axon with the lowest longitudinal resistance in a peripheral nerve cross section would have a large diameter and extensive myelination, facilitating efficient and fast signal transmission.

Explanation:

When, 1 gram of hemoglobin in the capillaries in the lungs will be combined with 1.34 mL of oxygen.

To determine how much oxygen 1 gram of hemoglobin in the capillaries in the lungs will be combined with, we need to make some assumptions and calculations.

Assumption 1; The oxygen-binding capacity of hemoglobin is 1.34 mL of oxygen per gram of hemoglobin.

Assumption 2; The oxygen saturation of hemoglobin in the capillaries in the lungs is 100%.

Given that 1 gram of fully saturated hemoglobin is combined with 1.3 cm³ of oxygen, we can convert cm³ to mL:

1.3 cm³ = 1.3 mL

Using assumption 1, we know that 1 gram of hemoglobin can bind with 1.34 mL of oxygen. Since the oxygen saturation in the capillaries in the lungs is 100%, we can multiply the oxygen-binding capacity by the weight of hemoglobin:

1.34 mL/g × 1 g = 1.34 mL

Therefore, 1 gram of hemoglobin in the capillaries in the lungs will be combined with 1.34 mL of oxygen.
