If number of electrons in an atom is 8 and number of protons is also 8, then
(i) what is the atomic number of the atom? and
(ii) what is the charge on the atom?
Answer:
i) 8
ii)0
Explanation:
The equal nos of the electrons and protons means it's not a ion, which makes the atomic number equal to them.
Since it is not an ion, the charge shall be 0 since it is neither positively nor negatively charged. The overall charge of an atom is neutral too.
Answer:
(i) atomic number = number of protons = number of electrons = 8
(ii)atom will be neutral (no charge) because number of protons(+) is equal to the number of
electrons (-).

Identify and describe the three ways the mutations affect organisms
Answer:
they may cause the development of a disease-causing allele
they may cause the development of a more beneficial allele
they, in some cases, may have no noticeable affect.
Explanation:
Answer:
Mutations may be beneficial, harmful, or neutral to organisms. If the change caused by a mutation is useful to the organism, then it is beneficial. If the change is damaging to an organism, then it is harmful. If the change is neither useful nor damaging, then the mutation is neutral.

Calculate by what percentage did the captive population of golden lion tamarins increase between 1970 and 2007?
Answer:
The captive population of golden lion tamarins increase between 1970 and 2007 is explained below in detail.
Explanation:
In the early 1970s, there were 91 lion tamarins in 27 distinctive zoos. Biologists created a strategy to improve the species' survival. The purpose was to improve the quantity and biogenetic variety of lion tamarins. As of 2007, there were 497 lion tamarins in 144 terrariums around the globe. Further, about 154 tamarins from the program have been re-presented to the wild since 1984. These tamarins are components of a strong wild population of more than 651.
12. In guinea pigs, the allele for short hair is dominant.
What genotype would a heterozygous short haired
guinea pig have?
What genotype would a pure breeding short haired
guinea pig have?
What genotype would a long-haired guinea pig have?
Answer:
What genotype would a heterozygous short haired
guinea pig have? Ss
What genotype would a pure breeding short haired
guinea pig have? SS
What genotype would a long-haired guinea pig have? ss
Explanation:
I just used S to substitute for my alleles, but you can use any letter. (For example: Ee, EE, ee)
If H is the dominant allele for short hair, we would have the followng genotypes:
Heterozygous short haired: Hh
Pure breeding short haired: HH
Long-haired guinea pig: hh
What is a Dominant Allele?A dominant allele is an allele of a trait that always expresses itself in the presence of a recessive trait in an allelic pair. Capitral letter is usually used to denote the dominant allele.
Let H represent short hair (dominant allele)
h represents long hair (recessive allele)
Therefore, we would have the following:
Genotype for heterozygous short haired would be: Hh
Genotype for pure breeding short haired would be: HH
Genotype for long-haired guinea pig would be: hh

**Urgent** Will mark brainliest!
Answer:
Although these two animals are both bears, clearly they are entirely different. Becasue they live in pretty much opposite environments, they developed individual traits so they could survive, which is called adaption. While the polar bear's thick fur and fat serve as great protection against the cold, it wouldn't be very helpful in hot climates. And the sun bear, with it's short hair and lack of protection, would freeze to death in the polar bear's environment. Each animal, over time, has to develop new traits that allow it to adapt to it's particular environment.
Answer:
These 2 different types of polar bears, may be the same type of animal, but as given in that text, they differ. These 2 different types of polar bears have different types of survival skills, in order to adapt to their environment. The Polar bear in the Northern Hemisphere has very thick fur, and other thick parts in it's body to keep them warm in the ice-covered areas that it lives in so that it wont die, due to the cold. While on the contrary, the bear in the tropical rainforest only has short hair, to keep them at a just-right temperature, so it wont die due to how hot it is. If both of these bears were to switch their environment, then they will die easily since they are not well adapted to that environment.

Max tried an experiment in which he added red-dyed salt water to clear freshwater. He noticed that a lot of the red water sank below the clear water. Which of the following statements explains why this happened?
a. Adding salt to water makes it more dense.
b. Adding salt to water makes it less dense.
c. Adding salt to water decreases its temperature.
d. Adding salt to water increases its temperature
Answer:
A
Explanation:
Adding salt to water causes its density to increase. Denser water will sink below less dense water.
As salt water is denser and will sink at the bottom and adding the salt raises the temperature of water body and hence will make it more warm and saline.
A max tries to add red dyed salt water to clear the fresh water he sees a red color sinking below the fresh water that is cool.The option D is correct.

Answer:
27 grams
Explanation:
27 grams of salt would still be left behind.
The dissolution of salt in water is a physical reaction and the salt can be recovered by evaporating off the water using appropriate procedures.
Provided that no part of the salt/water mixture is lost during the process of evaporation, if 27 grams of salt was dissolved initially, the same amount of salt would be recovered at the end of the separation process.
