Hi there!
The mass of an object stays constant no matter where it is. Therefore, the mass of an object as it moves away from the center of the earth stays the same.
I hope this helps! Let me know if I can clarify.

Which of the following is NOT a main reason myths were an important part of everyday life in ancient Greece? Group of answer choices They gave them something to do. They explained religious rituals. They explained the weather. They gave meaning to the world
Answer:
They gave them something to do.
Explanation:
What is the name of the process that occurs in
the core of the sun producing the light and heat
energy for life as we know it on planet Earth?
For example, hydrogen atoms are fused together to form helium. In the process, an immense amount of heat and energy is released. Much of that energy is on the electromagnetic spectrum that we cannot see (eg: ultraviolet light), but the visible portion of the spectrum is what we can see and that produces the yellow glow of the sun.
A woman has blood Type A, her baby has blood Type AB: Is it possible that a man who has the blood Type A could be the father? Show the Punnett Square and explain.
Answer:
No, it is not possible
Explanation:
Humans use the ABO blood group system where the A and B alleles are dominant over allele O but codominant with one another.
This system is such that;
Type A can only have genotype: iAiA or iAi
Type B can only have genotype: iBiB or iBi
Type AB can only have genotype: iAiB
Type O can only have genotype: ii
According to this question, a woman has blood Type A (iAiA or iAi) and her baby has blood Type AB (iAiB). This means that the father definitely contributed the allele B in order to have a baby with type AB. It also means that, according to the question, IT IS NOT POSSIBLE FOR A "Type A" father to produce that baby (see the punnet square attached).
Note: The father must contain an allele B in his genotype i.e. the father must be either type B (iBiB or iBi) or type AB (iAiB)

It is an
advantage for two species to share the same niche.
Answer:
False.
Explanation:
The competitive exclusion principle states that when two species compete for exactly the same resources (thus, they occupy the same niche), one is likely to be more successful. As a result, one species "outcompetes" the other species, and eventually the second species is eliminated.

In an experiment, Dr. Travis examined the effects of calcium intake on osteoporosis, a condition that causes an increased risk of bone fractures. The amount of calcium is what
variable. The risk of bone fractures can be changed by what?
.
Answer:
By consuming necessary amount of calcium per day.
Explanation:
The amount of calcium is recommended for adults are 1000 mg per day whereas for aged people, it should be 1200 mg per day and for children it becomes 1300 mg per day in order to make the bones stronger and avoid the risk of fracture. The risk of bone fractures can be changed by consuming the recommended amount of calcium through your diet.
What are the similarities and differences between plant, animal, and fungal cells?
Answer:
They are eukaryotic cells, they present the three main parts: cell or cytoplasmic membrane, cytoplasm and nucleus defined with chromosomes and nucleolus. The three types of cells have in common the following structures: cell membrane, cytoplasm, nucleus defined with chromosomes and nucleolus, mitochondria, smooth and rough endoplasmic reticulum, ribosomes, Golgi apparatus, cytoskeleton and peroxisomes. But it differs in some. The plant cell has chloroplasts and a cell wall and the animal cell does not.
Explanation:
The animal cell has centrioles, lysosomes. It has no plastids, no cell wall, it has vesicles. They do not have the ability to produce their own food from inorganic components. The plant cell has plastids (chloroplasts), cell walls, large vacuoles. Fungal cells are organisms without chlorophyll, therefore they cannot photosynthesize. The reserve substances of the cytoplasm are not starch granules. As they are not able to synthesize their food, they have to obtain from other living organisms (they feed on other plant and animal residues contributing to decomposition) that is, they are heterotrophic. Fungal cells have a cell wall that is not present in animal cells and but plant cells have a cell wall. They have lysosomes and centrioles that the plant cell lacks but they are in animal cells. Animal cells, with a few exceptions, do not have vacuoles while plant cells do. The three types of cells have present nucleus, membrane, mitochondria, endoplasmic reticulum, Golgi system.

how do I figure out how to find the nucleus
Answer:
The mass number is the sum of protons and neutrons. This means to find the number of neutrons you subtract the number of protons from the mass number. On the periodic table, the atomic number is the number of protons, and the atomic mass is the mass number.

1. What are some examples of different types of
asexual reproduction?
2. What are some types of advantages of asexual reproduction?
3. What are some of the disadvantages if asexual reproduction?
4. What is sexual reproduction?
5. What are alleles?
6. Which has greater variation, asexual reproduction or sexual reproduction?
Answer:
a) There are a number of types of asexual reproduction including fission, fragmentation, budding, vegetative reproduction, spore formation and agamogenesis. Spore formation occurs in plants, and some algae and fungi, and will be discussed in additional concepts
b) The advantages of sexual reproduction:
.) produces genetic variation in the offspring.
.) the species can adapt to new environments due to variation, which gives them a survival advantage.
.) a disease is less likely to affect all the individuals in a population.
c) The disadvantages of asexual reproduction include:
.) it does not lead to genetic variation in a population.
.) the species may only be suited to one habitat.
.) disease may affect all the individuals in a population.
d) the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).
e) each of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
f) Sexual reproduction gives rise to more viable variation than asexual reproduction. Because in sexual reproduction, genetic material from both the parents mixed (recombination of parent chromosomes) by fertilization...

What could happen if two of the base pairs on this strand of DNA were switched?
In the DNA structure if the two base pairs exchange it leads to creating a mutation in the sequence and makes different proteins, hence option A is correct.
How do DNA base pairs change the protein?A mutation is any kind of change that leads to the creation of an abnormal protein, DNA has genetic information to synthesize any kind of protein.
The process of transcription by which genetic information stored in the DNA is passed to the RNA, which translate this information to make the protein.
Protein is the final output of the genetic information stored in the organism's cell, if any change in the DNA sequence it affects the final functional structure of the protien.
Therefore, different protein is the result of the base pairs on this strand of DNA being switched.

Sickle Cell anemia is a recessive trait that causes blood cells to be misshaped. A woman who has no history of sickle cell anemia marries a man whose father had sickle cell anemia. What are their genotypes?
Answer:
See the answer below
Explanation:
Let us assume the sickle cell anemia allele to be S and the alternate, non-sickle cell allele to be A.
Since the woman has no history of sickle cell in her family, she is totally free from the trait and, hence, would have the genotype of AA.
The man's father had sickle cell anemia. This means that the man has, at least, one sickle cell allele in his genotype with the other allele depending on the genotype of his mother. Hence, the man can be AS or SS depending on the genotype of his mother.
