Explanation:
In 1831, Charles Darwin visited the Galapagos Islands While observing the giant land tortoises that lived on these islands, Darwin noted that the shape of the tortoise shell varied depending on which island the tortoise lived. Tortoises on one island had round shells, for example, whereas tortoises on aneighboring island had more flattened, saddle-shaped shells. Which statement BEST summarizes Darwin's explanation for these differences?
A) Random mutations caused the shape of the shells to fluctuate periodically.
B) The shape of the tortoise shell varied because the predators on the islands were all similar.
C) The particular shape of the shellwas best suited for the island on which the tortoise was living.
D) Tortoises who used their shells in special ways caused the shells to become larger, rounder, or flatter.

In the middle of the night, you are awakened by hunger pains. You proceed to get up and go to the kitchen to have a couple of cookies and a glass of milk. Satisfied you go back to bed content. Explain in detail what tissues, organs, and organ systems are involved in completing that task. Be sure to include how the systems interact. The more detail the better! Start with getting up to get the food and include details on the steps in how the food gets digested.
Explain in detail
Answer:
Mouth, stomach, liver, pancreas and small intestine.
Explanation:
If we eat these foods which have carbohydrates, its digestion starts from the mouth because the saliva present in the mouth mixes with the food and start its digestion. When the food reaches to the stomach, the foods are broken down into micromolecules with the help of enzymes secreted by liver and pancreas. After that the food goes to the small intestine where absorption of nutrients and water also occurs.

1. Consider the statement: "Sickle cell disease is a(n)
disease."
Which of the following terms could fill in the blank to make the statement true? Write "yes" or "no" next to each
possible response. There may be more than one correct answer.
Genetic
Infectious
Potentially lethal
Inherited
Answer:
Genetic = yes
Infectious = no
Potentially lethal = yes
Inherited = yes
Explanation:
"Sickle Cell Disease" is a blood disorder that is mostly inherited. An example of this is the "Sickle Cell Anemia," which means the body of the person is lacking in red blood cells. In order for an infant to carry such disease, both of his parents must pass the defective gene to him. It is a potentially lethal or deadly disease because if not given remedy, it may lead to several complications such as organ damage, leg ulcers, blindness, etc.
It is not infectious, which means that a person with a Sickle Cell Disease cannot transfer it to another person. It is not likely to spread as well.

Why are linked traits inconsistent with Mendel's laws?
Answer:
Linked Genes Violate the Law of Independent Assortment. Although all of Mendel's pea characteristics behaved according to the law of independent assortment, we now know that some allele combinations are not inherited independently of each other.
Explanation:
PLz, mark me as a brainlist :)
Mendel studied the transmission of genes in peas(pisum sativum) that were placed on different chromosomes. During meiosis there are two types of recombinations that make sure the offspring is different from the parent. First intrachromosomial recombination (crossing-over)where genetic material is exchanged between chromosomes. And interchromosomial recombination when homologous chromosomes are separated.
In Mendel's experiments only interchromosomial recombination was considered, but when Thomas Hunt Morgan experimented with Drosophilla Melanogaster he didn't get the same results because he focused on genes that were placed on the same chromosome. In this situation crossing over influenced the results.
Spider monkeys in Costa Rica live in rain in the rain forest where they eat fruit and nuts from big forest trees the trees also protect them from predators like jaguars and large snakes the trees are the spider monkeys
Answer:
The correct answer is - habitat and niche.
Explanation:
The spider monkey gets a place to live in rain, and fruit to eat, and also protection from predators like the jaguar and large snakes from the big forest trees. All these characteristics are the characteristics of the habitat of an organism.
It also explains the position of the spider monkey in the ecosystem and explains how it interact in the ecosystem which is the characteristic of the niche of an organism.

if the stomata could not close , would that be a good or bad thing for the plant?
Answer:
Transpiration is the process of evaporation of water from the leaves and stems to the atmosphere. The stomata close when the guard cells shrink, which in turn ceases the transpiration. Opening of stomata allows the process of transpiration, so the root cells do not die.
But if it can't close:
The downside to wide open stomata is increased water loss (transpiration). So stomata of cool-season turf grasses have decisions to make. The plant needs to capture and store energy via photosynthesis, however, excessive water loss through transpiration can result in plant injury or death.
It's a bad thing.
There is a population of 1,000 wolves. Over the course of a year 100 wolves are born.
What is the birth rate?
•0.1 births per individual per year
•10 births per individual per year
•1.0 births per individual per year
•0.01 births per individual per year
Answer:
10
Explanation:
Because 1,000 divided by 100 equals 10.
There is a population of 1,000 wolves. Over the course of a year, 100 wolves are born. The birth rate is 10 births per individual per year. The correct option is b
What is the birth rate?Birth rates of organisms decline and mortality rates increase in density-dependent populations due to numerous factors affecting the rate of reproduction and survival.
When there is a disease, competition, or predation in that organism, it has a higher mortality rate and a lower growth rate. These three factors reduce the birth rate and raise the death rate in an organism's population.
If both the death and birth rates are low, the population will not grow significantly and will remain relatively stable.
1000 / 100 = 10
Therefore, the correct option is b, 10 births per individual per year.

They are modified by changes in moisture, can conclude about the molecules responsible for these responses
what is moisture ?moisture is defined as the presence of liquid in an environment, all liquids, which means water and typically in trace amounts.
The trace amount of water could be in wood, food products, or just about anything, the moisture is used to indicate the presence of water in the air, whereas humidity is more accurate.
the impact of Moisture is significant whereas the high moisture content can cause damage to a building and may even cause health problems for the occupants.
There are already different types of materials that can help in preventing unwanted moisture depending on factors such as water vapor diffusion, airborne water movement, capillary suction, and gravity.

What is the correct pathway that food travels during digestion? *
a. Mouth, stomach, esophagus, small intestine, large intestine
b. Mouth, esophagus, small intestine, stomach, large intestine
c. Mouth, esophagus, stomach, large intestine, small intestine
d. Mouth, esophagus, stomach, small intestine, large intestine
The correct pathway that the food travels during digestion is Mouth, esophagus, stomach, small intestine, large intestine. The correct option is D.
What is alimentary canal?The gastrointestinal tract (also called the digestive tract). This long tube of organs serves as a conduit for food to pass through the body. It includes the esophagus, stomach, and intestines and runs from the mouth to the anus (where poop comes out).
The digestive system's alimentary tract is made up of the mouth, pharynx, esophagus, stomach, small as well as large intestines, and rectum.
The alimentary tract's primary function is to convert food into absorbable particles and transport them to the body's other organs.
The correct digestive pathway is the mouth, esophagus, stomach, small intestine, and large intestine.
Thus, the correct option is D.
