Wind energy is a reusable resource of energy thus, is environmentally useful. As reusable, it doesn't give off any type of gas/heat energy harmful to the environment/ the ozone layer, it is considered an eco-friendly source of energy. But, as wind energy requires turbines, and turbines require wind, the wind and air pressure of the area matters as more the wind, more effective the wind energy. Wind energy and other reusable sources are often referred as economically expensive as installing the turbines over large plots of land is expensive and also reduces the area for home building etc, leaving more homeless people.

Where does the po32– come from that circulates due to upwelling? select all that apply.

IRISSAK [1]

Answer: a. dead organisms from the marine food web.

c. liberation through ATP hydrolysis in living organisms.

Upwelling is a wind driven motion of lower bottom nutrient rich and warmer water on the surface of the water body. This wind driven motion facilitates the movement of nutrients available for growth of primary producers like phytoplanktons growing on the surface of water body. The dead organisms from the marine food web get decomposed and the organic matter obtain after decomposition is a rich source of phosphorous. This phosphorous gets transferred to the upper layers of the water body by upwelling. In aquatic organisms ATP hydrolysis occurs which is a catabolic process that uses water to split the bonds present in the ATP molecule and hence, releases energy for functions performed by them along with a release in phosphate atom. This phosphate gets mixed with the water. Therefore, PO32 come from dead organisms from the marine food web and liberation through ATP hydrolysis in living organisms that circulates due to upwelling.

attashe74 [19]

Answer:

The correct answer is "each of the MHC genes has a large number of alleles, but each individual only inherits two for each gene".

Explanation:

In normal conditions, an individual has only two different alleles for a given gene: one inherited from his mother and the other from his father. However, this does not mean that among humans, there are only two different alleles for each gene. The major histocompatibility (MHC) genes are a clear example of this, since there are multiple combinations for each MHC class. For instance, there are 40 very similar alleles only for the HLA-B27 subtype.

Match the following terms and definitions.

nlexa [21]

Answer:

1. Oblong cells with unevenly thickened walls for support in young stems →

Collenchyma .

2. a waxy substance covering most surface areas of plants; helps to retain water → Cuticle.

3. The youthful, undifferentiated cells of root and shoot tips and other plant parts that produce new cells for growth → Meristem .

4. The most common plant cell, found in practically all parts of the plant body; important for food production, food storage, lateral transport, and other life processes; an almost round cell in some tissues → Parenchyma .

5. Dermal layer made of dead cork cells → Periderm .

6. Tiny holes in a cell wall which allow the passage of chemicals between cells → Plasmodesmata.

Explanation:

This all refers to tissues found in plant organisms.

In plants, the colenchyma is a supporting tissue, composed mainly of elongated, irregularly walled living cells with a large amount of cellulose. Their composition and the way they are arranged - with longitudinal interlacing - give the tissue strength and resistance. It represents one of the three basic tissues of plants.
Cuticles of plant tissue are formed by an oily secretion from the epidermal cells, forming a waxy, impermeable and protective layer, which prevents the entry of foreign organisms and reduces the loss of water from the plant. The cuticles are mainly composed of cutin molecules associated with wax.
Meristematic tissue represents a group of undifferentiated cells with great capacity to multiply, differentiate and provide growth and development to a plant. It is a tissue with unlimited growth capacity, which allows the plant to always replace the damaged tissue and grow indefinitely.
Parenchyma of plant organisms are tissues that are found in most of these organisms, allowing multiple functions, such as the drying of substances, storage and photosynthesis. The parenchyma is generally formed by thin-walled living cells that can adapt to any vital function of plants.
Periderm constitutes the outer coating of a plant or bark, functionally replacing the epidermis. This tissue is located after the secondary phloem, and is composed of cork, specifically phellem, phellogen and phelloderm.
Plasmodesmata are a type of microscopic channel that crosses the plant wall, being a link for intercellular communication, as well as the transport of nutrients.
