Blizzard [7]4 years ago

Answer:

The correct option is A. Steroid hormones exert their action by entering the nucleus of a cell and initiating or altering the expression of a gene.

Explanation:

Steroid hormones are derived from cholesterol and regulate multiple biological processes. All steroid hormones exert their action by crossing the plasma membrane and by binding with their respective intracellular receptors. They stimulate cell growth in a very different way, their lipophilic nature gives them the ability to cross lipid barriers, so, without the need for extracellular signals, these hormones can easily enter the cell, cross the cytoplasm and reach the nucleus. There they bind to specific receptors that are associated with DNA promoter regions, modifying their structure and promoting the expression of the genes under their control.

Wind power, water power (also called hydroelectricity), solar power, ethanol:
lora16 [44]
Wind power:

Advantages:

-Using wind as a source of power is very cost-effective. This is method is fuel free and the electricity harvested from wind farms is sold at a fixed price over a long period of time.

-Wind power is a clean fuel source. Using wind as a source of power prevents air pollution unlike power plants that mostly rely on fossil fuels which releases toxins into the hair causing both environmental and health problems.

-Wind power is a sustainable source of power since nothing can really stop it from being produced. Since this source of power relies on air, as long as there is air, energy can be harvested.

Disadvantages:

-Wind turbines are usually built in rural areas due to the size of them and the amount of space needed to build them. Because of this, they aren’t usually close to cities or remote locations where the energy harvested from them is most needed.

-Wind turbines can harmfully impact nature. Because of their height and size, many birds and other flying animals end up getting killed by the spinning blades connected to the turbine.

-Locations to build wind turbines may be hard to get due to competition with other things that may be of more importance on the land compared to wind farms.

Sweet pea plants have a diploid 2n chromosome number of 14.
pashok25 [27]

The sweet pea plants having a diploid 2n chromosome number of 14 produces F1 offspring with 14 chromosomes by the process of fusion of gametes each having n number of chromosomes.

<h3>What are diploid organisms?</h3>

Diploid organisms are organisms having two copies of each chromosome or 2n number of chromosomes

Diploid organisms undergo meiosis to produce haploid cells having n chromosomes.

Two haploid cells from each parent combine to produce offspring with 2n number of chromosomes.

Therefore, the sweet pea plants having a diploid 2n chromosome number of 14 produces F1 offspring with 14 chromosomes by the process of fusion of gametes with n number of chromosomes.
