Why do you think that dilating blood vessels will decrease temperature of the blood as well as decrease blood pressure?

Answers

Dilation of blood vessels will cause them to be nearer to the skin surface. This means that it will be easier for heat to be lost from the blood vessels to the skin and ultimately to the atmosphere via conduction. This loss in heat reduces the temperature of blood and hence the body temperature in general.
If the rate at which blood is pumped is constant (whether blood vessels are constricted or dilated), then blood pressure decreases when blood vessels are dilated because blood pumped at constant speed has more space to pass resulting in decreased blood pressure.

what is the part of endoplasmic reticulum without proteins attached?

Answers

Answer:

Regions of ER that lack bound ribosomes are called smooth endoplasmic reticulum, or smooth ER.

Answer:

The ER regions lacking bonded ribosomes are referred to as the smooth or smooth endoplasmic reticulum.

Explanation:

The Endoplasmic reticulum is a membrane network within the cell that transmits proteins and other molecules. Proteins called ribosomes are assembled at organelles. The ribosomes that are assembled to the endoplasmic reticulum give it a rough look when proteins are intended for cell membrane or export from the cells. Smooth endoplasmic ribosomes are absent and help to synthesize and concentrate various cell-required substances.

Either a smooth or rough endoplasmic reticulum is capable of producing protein in general for the rest of the cell to function. The raw endoplasmic reticulum contains ribosomes, small, red organelles that make these proteins. Sometimes the proteins remain inside the endoplasmic reticulum when made incorrectly.

It is retained and the endoplasmic reticulum is engulfed because it appears to be stuck in a way that does not lead the protein where it is supposed to go. There is also the smooth endoplasmic reticulum on which these ribosomes are not contained. This smooth endoplasmic reticulum produces other materials that the cell needs. The endoplasmic reticulum is an organelle that actually produces proteins and substances that are necessary for the rest of the cell.

Why don't whales have saliva?
______
Kinda curious to know! :3​

Answers

The seawater dilute the saliva in them, so the necessary digestive enzymes they can't use.

This elasticity helps cetaceans to renew 90% of the air in their lungs in a single breath. The gene SLC4A9 is partly responsible for the production of saliva in terrestrial mammals, but your average dolphin or whale has little need of spittle which is why it has been lost in cetaceans.

Scientists have made estimates of the loss of biodiversity in the Mediterranean Sea, and this is due to human interference, climate change will increase the loss of biodiversity, habitat degradation, and exploitation of species, so answers A, C, D, and E are all correct.

What is the significance of the loss of biodiversity in the Mediterranean?

Biodiversity is low in almost every region of the world due to rapid urbanization, which has resulted in the rapid loss of plants and animals as well as a decline in their numbers due to habitat loss, and they are further impacted by climate change.

Hence, scientists have made estimates of the loss of biodiversity in the Mediterranean Sea, and this is due to human interference, climate change will increase the loss of biodiversity, habitat degradation, and exploitation of species, so answers A, C, D, and E are all correct.

A construction company wants to trap pollutants in runoff at its sites. What should the company do?
O A.
Practice conservation tillage at the sites.
O B. Release beneficial insects,
such as spiders and ladybugs, at the sites.
O C. Plant grass and
lay straw at the sites.
O D. Plant trees at the sites.

Answers

Answer:

O C. Plant grass and  lay straw at the sites.

Explanation:

Plant grass and  lay straw at the sites are used by the company to trap pollutants at its sites because these plants reduce the runoff by absorbing most of the water and by absorbing water we can trap the pollutants present in that water. By trapping this industrial water, we can reduce water pollution that occurs due to this industrial waste and pollutants so planting grass and lay straw is the best way to trap pollutant.
