Answer:
The beaker has more water.
Explanation:
The beaker which has more water takes more time to reach the room temperature because it has more surface area than other one. If a body has less surface area then it will lose heat energy quickly and to reach its room temperature as compared to the body that has more surface area. Heat transfer depends on the materials in which it is placed and the surrounding environment. In some materials conduction of heat occurs quickly as compared to other materials.
Answer:
c 500000
Explanation:
the half was 1000000 so it's 2000000 and 25% of that is 500000
Answer:
Compound microscopes have more than one lens to generate high magnification images of flat, thin specimens. There are three major structural parts of a microscope: Head, Base, and Arm. ... The light is then collected and formed an image by an objective lens. We see the magnified images through the eyepiece
Explanation:
Acute transfusion reactions usually have symptoms within 24 hours of having the blood transfusion. When there is a transfusion reaction, the transfusion should be stopped right away and a normal saline solution be given as an Intravenous fluid. Corticosteroid or Diphenhydramine medications may help taper the symptoms.
The fact that there is little diversity in the form of mc1r gene we can inferred that it is an that it is an advantageous trait to protect from extreme sun and lack of diversity is due to the negative selection.
- The MC1R gene give order for formation a protein called the melanocortin 1 receptor. This receptor plays very important role in normal pigmentation. The receptor is found on the surface of melanocytes, these cells secrete a pigment called melanin. Melanin is that the pigment that gives skin, hair, and eyes their colour.
- Negative selection works to get rid of deleterious alleles from a population in another term that describes this is often “purifying selection.”
- Positive selection leads to directional selection. Positive selection for a beneficial allele can increase the frequency of neutral variants neighbouring the beneficial allele; such genetic hitchhiking may end in a large area of homozygosity (i.e., loss of diversity during a large area of a chromosome) due to a highly advantageous mutation and is referred to as a selective sweep.
