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 (-).

Read the information below. You just scratched a mineral sample with your fingernail. Your fingernail measures 2.5 on the Mohs scale and fluorite measures 4 on the Mohs scale. Explain why the mineral sample you have cannot be a piece of fluorite
Please help me I need to write a 3 sentence
Answer:
It can't be fluorite because your fingernail is less on the Mohs scale than fluorite. When an object is less than another object on the Mohs scale it doesn't leave a scratch on the other object. Therefore if your finger leaves a scratch on the material then it has to be less than 2.5 on the Mohs scale. Fluorrite is not less than 2.5 on the Mohs scale so it is impossible that it is that mineral.

How do animals get nitrogen that is stored in the soil?
O A) Animals do not take in the nitrogen stored in the soil.
O B) Bacteria change the nitrogen into a gas that the animals breathe.
OC) Plants ab orb the nitrogen from the soil and animals can eat the plants.
O D) The animals can eat the soil and absorb the nitrogen through their digestive system
Answer: C) Plants absorb the nitrogen from the soil and animals can eat the plants.
Heterotrophs, specifically herbivores and omnivores, are animals that eat plants (autotrophs) to get the nutrients they need. Those that eat the plants get the nitrogen from the plant that has absorbed it from the soil. Omnivores and carnivores eat the herbivores to get nitrogen that way. For more more information, take a look at the nitrogen cycle.
A person was hit over the head with a baseball bat during a riot and was killed. The victim was also run over by a car before health had arrived, but was already dead. During the autopsy, he was found to have a broken finger, which it already started to knit itself back together. What was the manner of death?
Answer:
He died as a result base ball bat that was hit on his head and He sustained perimotem injury
Explanation:
This is because, during the root, The person was hit by base ball bat and thus make the person to sustain injury and it result to His death. Perimotem injury refer to injury a person sustained before His death. He died as a result of the injury he sustained during the riots and that lead to his death at the spot before getting to the hospital.
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.

What primary method does the cell employ to ensure gene expression only occurs when necessary?
Limited amounts of specific DNA
Phosphorylation cascade with multiple steps
Receptors that only fit specific hormones
Unique transcription factors made of carbohydrates
Answer:
Unique transcription factors made of carbohydrates
Explanation:
Gene expression refers to the way by which the genes which contain hereditary materials in the cells are converted to certain proteins. Gene expression is regulated to avoid the wastage of useful energy. Transcription allows the copying of genetic information from the DNA to the RNA.
Transcription factors can activate or deactivate a gene thus hindering its expression. Unique transcription factors help to regulate gene expression.
Answer: receptors that only fit specific hormones
