What do you call the overall force acting on a object
Answer:
It's called a resultant force.
Explanation:
You see, there may be more than one direction of a force acting on an object so if both forces are of equal strength, the object doesn't move, but if one force is stronger than the other, the resultant force would tilt towards that force and the object would move that direction. It is the resultant force that decides where the object would go based on the forces acting on it.
Ou are studying evolution by drift of coat color in two other wild populations of Dornish Sand Steeds. One population lives near Sandstone and the other near the banks of the Greenblood River. Knowing nothing else about these populations, which population would you conclude is more susceptible to genetic drift? Make sure you explain your reasoning and show your calculations. H
Answer:
The Sandstone community is somewhat more vulnerable to gene flow. A further explanation is provided below.
Explanation:
The risk of random mutations increases typically higher throughout communities with either a greater concentration. Genetic variation describes the probability including its loss of individual proteins from either the species. The lower the chromosomes, the increases the likelihood. Although women and men remain increasingly crucial for the sustainability of the community. Brown genotypes throughout Sandstone individuals will now have a greater risk of being attacked by gene flow.What do you think the term "ecological footprint" means?

what are two types of cells? and what is the diffrenece between both of them? HURRY IM FAILING
Answer:
There are two cell types: prokaryotes and eukaryotes. Prokaryotic cells are usually single-celled and smaller than eukaryotic cells. Eukaryotic cells are usually found in multicellular organisms, but there are some single-celled eukaryotes.
If this helped mark my answer the brainliest, (by clicking the little crown on my answer), it really does help a lot ! (〃＞＿＜;〃)Answer:
The two types of cells is Prokaryotic and Eukaryotic cells.
Prokaryotes are organisms that consist of a single prkaryotic cells. Prokaryotic cells have only one organelle: the ribosomes.
Eukaryotic cells are found in plants, animals, fungi, and protists. They ange from 10-100um in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing the eukarytoic cells.

chemical reactions that absorbs more energy than they release are considered to be
Chemical reactions that absorbs more energy than they release are considered to be endothermic.
What is endothermic reactions?Endothermic reactions involve the absorption of heat from the surroundings, resulting in a decrease in temperature of the surroundings. In these reactions, the reactants have lower energy than the products, and the difference in energy is absorbed as heat from the surroundings. Examples of endothermic reactions include the melting of ice, the evaporation of water, and the reaction of baking soda and vinegar.
In contrast, exothermic reactions release more energy than they absorb, resulting in an increase in temperature of the surroundings. Examples of exothermic reactions include combustion reactions and the reaction between acid and base to produce salt and water.

What is the correct type of circulatory system for members of class Reptilia?
Open - Oxygen is delivered to organs by blood washing over organs in the body cavity.
Closed - Oxygen is delivered to organs by blood traveling through arteries and veins.
O Closed - Oxygen is delivered to organs by blood washing over organs in the body cavity.
O Reptiles don't have a circulatory system.
Answer:
Closed the first one
Explanation:
In amphibians, reptiles, birds, and mammals, blood flow is directed in two circuits: one through the lungs and back to the heart, which is called pulmonary circulation, and the other throughout the rest of the body and its organs including the brain (systemic circulation).
most mammals, have closed cardiovascular systems. The two main circulation pathways in invertebrates are the single and double circulation pathways.

What are the parts and primary function of the male reproductive organ?
Answer:
The male reproductive system is mostly located outside of the body. These external organs include the penis, scrotum and testicles. Internal organs include the vas deferens, prostate and urethra. The male reproductive system is responsible for sexual function, as well as urination.
Explanation:
The majority of the male reproductive system is found external to the body. The testicles, scrotum, are some of these external organs. The vas deferens, prostate, and urethra are internal organs.
What is the male reproductive system?The male reproductive system is made up of internal organs including the prostate gland, vas deferens, and urethra as well as external genitalia like the testes, and scrotum.
The health of the male reproductive system and the hormones secreted by the brain determine a man's fertility and sexual characteristics. The male reproductive system is in charge of both urine and sexual function.
They create, retain, and move sperm and semen, which are the male reproductive cells (the protective fluid around sperm).
Therefore, sperm is released into the female reproductive system by them. Male sex hormones are created and secreted by them.

A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.
What is nucleotide?It is the sub units and buIlding blocks of DNA. It is made up of a five-sided sugar, phosphate group and then a nitrogen base.
These groups make the backbone of the DNA helix. If you look at a DNA helix, they make the side of the ladder or the side portion. They connect to a nitrogen base which make the steps of the ladder. The type of sugar that is used in a DNA helix is called deoxyribose.
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine. Purines on the other hand make 5-sided and 6-sided rings.
Therefore, A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.

Scientists discover two planets orbiting a distant star. The average distance from the star to Planet A is 4 AU, and it takes 432 Earth days for Planet A to orbit the star. If it takes 1,460 days for Planet B to complete an orbit, what is the average distance from Planet B to the star?
Answer:
3.3
Explanation:
no reason for the explanation
Answer:
C. 9 AU
Explanation:
The period (T) of Planet A is 432365=1.2 Earth years. The period of Planet B is 1,458365=4.0 Earth years. Kepler's Third Law states that
a3=kT2
Substituting the known values of a and T for Planet A, we have
43=k⋅1.22
64=k⋅1.4
k=45.7
Using this value for k, we can solve for the distance from Planet B to the star
a3=45.7⋅4.02
a3=731.2
a=9.0AU
An alternative solution is to notice that a3T2=k for both orbits, which means that the ratio a3T2 is the same for both orbits. So, 434322=x314582. Solving this proportion gives x3=729, so x=9.0AU.
