Students observe woodchucks in their area. In the summer, students observe that woodchucks eat a lot of plants. In the winter,
students observe that woodchucks live in their burrows and are seen less often. The picture shows a woodchuck in its burrow.
Which change that helps a woodchuck survive the winter did students observe?
O A Woodchucks migrate to survive the winter.
O B. Woodchucks hibernate to survive the winter.
O c. Woodchucks eat a different kind of food in the winter.
O D. Woodchucks grow thicker fur to keep them warm in the winter.
Answer:
The correct answer is - B. Woodchucks hibernate to survive the winter.
Explanation:
Many mammals such as groundhog or also known as woodchucks hibernate during winter in order to survive winter. Hibernation is the process or state of minimal activity during a particular time of the year characterized by low body temperature, slow heart rate, and low metabolic rate.
Woodchucks are become less active and remain in their burrow and seen very little during the winter and stay like this till late winter or early spring.
what are the characteristic of cold blooded animal
Answer:
Cold-blooded animals, like reptiles, amphibians, and fish, become hotter and colder, depending on the the temperature outside. For example, when the sun sets at night, their bodies are cooler because it is less warm outside. When the sun is out, however, their bodies soak up the heat and become warmer.

compare the different types of sensory receptors and to predict the results of damage of each
Answer and I will give you brainiliest
Answer:
Sensory receptors are primarily classified as chemoreceptors, thermoreceptors, mechanoreceptors, or photoreceptors.
..
Damage to sensory receptors can result in a loss or alteration of the sense that the receptors are responsible for detecting, which can greatly impact an individual's daily life.
What are sensory receptors?Sensory receptors are specialized cells or structures that respond to specific types of stimuli, such as light, sound, or pressure. There are several types of sensory receptors, each of which is responsible for detecting different types of stimuli.
Photoreceptors, such as the rods and cones in the eye, detect light and are responsible for vision. Damage to these receptors can result in vision loss or blindness.Mechanoreceptors, such as those in the skin and inner ear, detect touch, pressure, and movement. Damage to these receptors can result in numbness, tingling, or difficulty with balance and coordination.Thermoreceptors, such as those in the skin, detect changes in temperature. Damage to these receptors can result in the inability to sense temperature changes and the risk of burns or hypothermia.Chemoreceptors, such as those in the nose and taste buds, detect chemicals and are responsible for the sense of smell and taste. Damage to these receptors can result in a loss of smell or taste, or an altered sense of smell and taste.Nociceptors, detect pain and are responsible for the sense of pain. Damage to these receptors can result in an inability to feel pain.Learn more about sensory receptors, here:

Imagine that we are interested in studying genetic and environmental influences on psychedelic mushroom consumption. For a group of twins, pairwise concordance is defined as C/(C+D), where C is the number of concordant pairs and D is the number of discordant pairs. In a study of 50 MZ twin pairs:
There are 2 pairs for which both twins have consumed mushrooms.
There are 38 pairs for which neither twin has consumed mushrooms.
There are 10 pairs for which only one of the twins has consumed mushrooms.
Required:
What is the MZ pairwise concordance rate?
Answer:
0.24 or 24 %
Explanation:
We know that from the given :
Pairwise concordant = [tex]$\frac{C}{C+D}$[/tex]
Here, C = concordant pairs
D = discordant pairs
Basically concordant pairs = both of twins consumed mushroom( [tex]$C_1$[/tex] ) + One of the twins consumed mushrooms ( [tex]$C_2$[/tex] ).
Concordant pairs = [tex]$C_1 +C_2$[/tex]
= 2 + 10
= 12
And in discordant pair, none of the pair consumed mushroom = 38
Therefore, pairwise concordance = [tex]$\frac{12}{12+38}$[/tex]
[tex]$=\frac{12}{50}$[/tex]
= 0.24
What element is in adenine that is not in
ribose?
Answer:
Nitrogen
Explanation:
Adenine is one of the four nitrogenous bases while Ribose is one of the two sugars (carbohydrates) that make up a nucleotide. Adenine is structurally composed of 5 carbon atoms, 5 hydrogen atoms and 5 nitrogen atoms to form the chemical formula C5H5N5 whereas ribose is structurally composed of five carbon atoms, ten hydrogen atoms, and five oxygen atoms to form the chemical formula; C5H10O5.
Based on the above explanation, it is evident that the element present in Adenine but not in Ribose is NITROGEN. Nitrogen is a major constituent of all nitrogenous bases (Adenine, Guanine, Cytosine and Thymine (Uracil).

E. Coli is a bacterium that lives in the gut of humans. The human provides the ideal habitat for e coli reproduction and the e coli provides the extra vitamin K that we use.
Group of answer choices
Parasitism
Predation (Predator-Prey)
Mutualism
Commensalism
Answer:
The correct answer is - Mutualism.
Explanation:
E. coli and humans have a parasitic relationship as these organisms cause harm to the Humans while they reproduce themself, however, E. coli also have a mutualistic relationship with humans that are present in the gut of the human's digestive tracts.
These bacteria help in providing vitamin k and nutrients to humans that is essential for the clotting of blood and the human provides the ideal habitat for E. coli reproduction.
