Answer:
They must shed their exoskeleton, or molt, in order to grow. The exoskeleton splits open. the animal emerges and swells to a larger size until the newer, larger exoskeleton is hardened.
Define monohybrid inheritance and law of segregation??
Please don't post invalid answer...!!
Answer:
In a monohybrid cross, both the alleles are expressed in the F2 generation without any blending. Thus, the law of segregation is based on the fact that each gamete contains only one allele. This law is based on four basic concepts: A gene exists in more than one form of an allele.

C. geographical distribution
d. genetic evidence
Answer:
c I hope I got it but have a good day
The type of evidence that should not be part of should be genetic evidence.
What is genetic evidence?It is the evidence where it predicted the no of human ancestors. Here the relation between the genetic diversity & the size of the population should be considered. So based on this, it received large no of observations and facts related to the fossil, anatomical, and the geographical evidence

based of these are true
A. Metal is denser than milk
B. Air and water are equal dense
C. Rain Water is less dense than fog
D. Orange Juice is denser than a whole orange
Answer:
A.
Explanation:
because solid metals will sink when placed on top of whole milk.
Metal is denser than milk is the property of density, these are true. Thus option A is correct.
What is density ?The density can be defined as its mass per volume and it is the ratio between mass and volume, where how much stuff of an object has in a unit volume.
Density is a calculation of matter, where it shows how tightly matter is mixed together, density was discovered by the Greek scientist Archimedes
The density of an object can be represented as the mass (m) can be divided by the volume (v)
Density = Mass/Volume
The SI unit of density is represented as kilogram per cubic meter (kg/m3) or in cgs unit it can be represented as grams per cubic centimeter (g/cm3).
Thus option A is correct.

How does global warming affect solar energy in the atmosphere?
-decreased ice causes less energy to be reflected
-decrease ice causes more energy to be reflected
-increased ice causes more energy to be reflected
-increase ice causes less energy to be reflected
Answer:
-decrease ice causes more energy to be reflected
Explanation:
Ice is Earth's most reflective substance. Thus, it helps the Earth reflect solar IR, keeping humans cool. Due to global warming , ice decreased causing less energy to be reflected. Therefore, option (A) is correct.
What is gobal warming?The long-term heating of the Earth's surface that has been observed since the pre-industrial period (between 1850 and 1900) is referred to as global warming. This warming is the result of human activities, most notably the burning of fossil fuels, which raises the levels of heat-trapping greenhouse gases in the atmosphere of the Earth.
The planet as a whole is experiencing an increase in temperature, and the poles are experiencing this increase at the quickest rate. As a direct consequence of this, ice sheets and glaciers are melting and receding. Therefore, although there is still a significant amount of snow and ice in the polar areas, there is a far smaller amount of it than there was in the past.
Therefore, option (A) is correct.

In a population of cats, a gene that controls an observable trait has several different alleles. Which of the following best explains how genetic drift might affect the genetic makeup of this cat population over time?
It is a directed process, so it might cause an increase in the gene pool's allele frequencies.
It is a nonselective process, so it might cause an allele to disappear from the gene pool by chance.
It is a random process, so it might cause a population to reach genetic equilibrium.
It is a selective process, so it might cause an increase in the population's genetic variation.
Answer:
It is a nonselective process so it might cause an allele to disappear from the gene pool by chance.

La respuesta correcta para esta pregunta abierta es la siguiente.
A pesar de que se te olvidó incluir las opciones o incisos para responder a tu pregunta, podemos comentar lo siguiente, basándonos en nuestro conocimiento sobre la materia.
Podemos pensar que la hormona que no produce este niño que sufre de gigantismo es la hormona llamada somatotropina. Esta hormona es muy importante durante el crecimiento y desarrollo del niño en la infancia porque secreta la adenohipófisis, una glándula vital para el correcto y proporcionado desarrollo en la etapa de la niñez.
Entonces, si no hay una secreción correcta de la hormona somatotropina, ésta hace que el niño desarrolle la condición llamada gigantismo.
Entonces podríamos decir lo siguiente.

describe how the intestines, liver, stomach, and pancreas all work together.
Answer:
They work together in the digestive system to make the food originate from the esophagus to the anus.
Explanation:
Answer:
Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins, along with your liver that makes a digestive juice called bile, which helps digest fats and some vitamins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. It also absorbs water with other nutrients. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.
Some extra info:
Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices.
Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts.
Liver. Your liver makes a digestive juice called bile that helps digest fats and some vitamins. Bile ducts carry bile from your liver to your gallbladder for storage, or to the small intestine for use.
Small intestine. Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.
Large intestine. In your large intestine, more water moves from your GI tract into your bloodstream. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.
