Answer:
Global warming
Explanation:
Global warming is defined as the heating of Earth's surface, atmosphere and oceans due to the result of human activity such as burning of fossil fuels that releases methane, carbon dioxide (CO2), and other greenhouse gases into the atmosphere.
Global warming is the result of action at one part of the world but it affects the other part of the world where human intervention is zero.
Due to global warming, there is extreme changes in climate which is resulting in melting of glaciers, rise in sea levels and loss of biodiversity.
Hence, the correct answer is Global warming.

Fossil evidence shows that vertebrates made the transition from water to land during the period.
Answer:
Devonian period
Explanation:
The currently available fossil evidence showed that vertebrates made the transition from water to land during the Devonian period. Specifically, the migration happened in the late Devonian period.
One of the features that enabled migration from water to land is the development of legs as against fins. While the latter is useful for movement in water, the former is necessary for locomotion on land.
In the late Devonian period, the first group of vertebrates with legs emerged. The tetrapods or four-legged vertebrates were known to have emerged about 330 million years ago and consist of the amphibians, reptiles, and mammals.
Describe the first interaction that triggers signaling to begin in a target cell.
Answer:
Target cell: this cell has a receptor that can bind the ligand. The ligand binds to the receptor and triggers a signaling cascade inside the cell, leading to a response. ... When a signaling molecule binds to its receptor, it alters the shape or activity of the receptor, triggering a change inside of the cell.

One type of muscular dystrophy, Duchenne muscular dystrophy, is is an inherited condition that usually only affects boys. Muscle weakness is noticed as children begin to walk or run. Characteristic signs include walking on tiptoe and large calves. The disease occurs in one out of every 3000 newborn male children. Why is this disease limited to mostly boys?
Answer:
Explanation:
Duchenne muscular dystrophy acts as a X-linked recessive disease. Which means the gene sits on the X chromosome, and you need two bad copies to show disease (for females) and one bad copy (to show in males).
Now from our knowledge, we know males are XY and females are XX. Males have only one copy of the X chromosome from their mother and one copy of the Y chromosome from their father, thus if they get the mutated version of the gene that causes this disease, they will get the disease. However, if a female has a mutated version of gene on one of the X chromosome, the other X chromosome could have a normal gene and that normal gene would take over and produce a normal phenotype/function.
Since, boys only have one X chromosome, if they get the mutated gene they will get the disease, whereas females have two X chromosome (so even if one copy is bad and the other is good, the good version can take over, however boys don't have this) thus mostly male children are affected by this.

Which of the following statements is incorrect?
1. The tracheal mucosa consists of pseudostratified ciliated columnar epithelium.
2 .The trachealis muscle and elastic connective tissue allow for changes in the diameter of the trachea.
3. The trachea is located posterior to the esophagus and extends from the larynx to the superior border of the fifth thoracic vertebra.
4. The trachea has incomplete hyaline cartilage rings.
Answer:
The trachea is located posterior to the esophagus and extends from the larynx to the superior border of the fifth thoracic vertebra.
Explanation:
This is a wrong statement. Anatomically ,this organ of upper respiratory system is located anterior to the oesophagus.Thus it is the oesophagus that is located posterior to the trachea.
It passes through the posterior mediastanium to branch into the left and right main bronchi.
it bends towards it ends to the right,which results in the crossing of the left main bronchus anteriorly to the oesophagus.
It is lined by mucus gland produced by pseudo stratified columnar cells and some ciliated and non ciliated cells.
The mucus helps in warming up inhaled air and filtration of the air of dust particles.
What kind of research method is are these?
Hypothetical Study 1
Researchers recruited 50 young adults (ages 18-25) who had recently been diagnosed with Type 1 diabetes, 50 who had recently been diagnosed with Type 2 diabetes, as well as 50 non-diabetic young adults, ensuring a comparable distribution of age, race/ethnicity, and gender across samples. They asked all of these participants as well as the participants' parents to complete a self-report measure asking questions about the participant's dietary and exercise habits between ages 15 and the present. They also requested participants' medical records indicating their body weight over time. Researchers found that the group with Type 2 diabetes was significantly more likely to have been overweight than either of the other groups as early as age 15. They also reported significantly higher levels of unhealthy eating habits as well as significantly lower levels of physical activity across this whole time period. Young adults with Type 1 diabetes did not differ significantly from the non-diabetic group across any of these measures.
Hypothetical Study 2
Researchers recruited 100 obese college students to participate in a weight-loss study. Participants were randomly assigned to one of three groups. The first group participated in a didactic course teaching them about healthy eating habits, exercise, and other types of self-care. The second group received the same training and also participated in a weight-loss support group. The third group was placed on a waiting list to participate in the training until after completion of the study. Researchers found that students in both the group that received didactic training only and the group that received both didactic training and a support-group lost significantly more weight throughout the course of the study than did those in the wait-list control group, but that they did not differ significantly from each other. However, at 6-month follow-up, they found that 90% of those in the group that had only received didactic training had regained the weight they had lost, whereas only 50% of those in the group that had also participated in the support-group experienced similar weight gain.
Hypothetical Study 3
Researchers asked 100 high school students to complete weekly self-report measures over the course of a year, asking questions about sleeping habits as well as general health questions. They examined the relationship between the number of hours of sleep students got on average and the number of days they were ill throughout the year. Researchers found that students' average number of hours of sleep per night was inversely related to the average number of days they reported being ill throughout the year. However, students did not seem to experience additional health benefits by sleeping more than 8 hours per night.

A) experimental
B) randomized, controlled trial
C) ex post facto
D) prospective ( i think it is this one)
E) retrospective
Answer:
1. option B
2. option A
3. option D
Explanation:
1. Which of these studies is an experimental study?
Yes, you got it right, it is study 2. Study 1 and 3 are just observational studies, where researchers collect and interpret data based on what they have seen, heard or observed. But for the experimental design, there is a manipulation on the part of the researchers where he grouped them and administered treatments.
2. Study 1 employs a retrospective design.
You also got that part right, Study 1 actually employed the retrospective design by sampling individuals and then collecting information about their past which in this case is asking questions about the participant's dietary and exercise habits between ages 15 and the present and also their medical records.
3. Study 3 employs a prospective design
You also got this right. Study 3 actually employed the prospective design by sampling individuals and follow them over time and data about them is collected as their characteristics or situations changes and in this context, they observed even after a change by sleeping more than 8 hours per night, students still did not seem to experience additional health benefits.

Which organism fix nitrogen in the soil ?
Answer:
Diazotrophs
Explanation:
The nitrogen-fixing bacteria and other micro organisms that fix nitrogen are collectively called 'Diazotrophs'. There are many strains of these bacteria in soil, which perform this function. They are important agents in the 'Nitrogen Cycle'.
There are two main groups of organisms that fix nitrogen in the soil: diazotrophs and cyanobacteria.
What are these organisms?Diazotrophics are bacteria that can convert atmospheric nitrogen into ammonia, which is a form of nitrogen that plants can use. Some examples of diazotrophs include Rhizobium, which is found in the root nodules of legumes, and Azotobacter, which is a free-living bacterium.
Cyanobacteria are photosynthetic bacteria that can also fix nitrogen. They are found in aquatic and terrestrial environments, and they can play an important role in the nitrogen cycle.

what is food , and the six classes of food
Answer:
Any nutritious substance that people or animals eat or drink or that plants absorb in order to maintain life and growth.
Explanation:
The food groups are divided based on the nutritional properties they offer. Foods that animals eat can be classified based on the amount of nutrients and the type of nutrients they provide for subsistence and survival. It is highly recommended to eat portions of food from the different groups in order to live a healthy lifestyle. This will provide you with a complete set of nutrients for better health.
There are seven major classes of nutrients and they are
carbohydrates
fibre
fats
protein
minerals
vitamins
water
These nutrient classes can be classified either into macronutrients or nutrients that are needed in large quantities and micronutrients or nutrients that are needed in small amount. Macronutrients include the carbohydrates, proteins, fats, fibre, and water while the micronutrients include vitamins and minerals.
Macronutrients provide the body with energy. Water and fibre are exempted. The energy is measures in terms of kilocalories or joules. Kilocalories are written as C in order to differentiate them with gram calories. For every gram of carbohydrate, seventeen kilo joules or four kilo calories are provided for your body. Fats provide your body with thirty seven kilo joules or nine kilo calories for every gram. Vitamins, fibre, minerals, and water do not provide the body with energy but they are needed for other purposes.
Carbohydrate molecules are made up of carbon, oxygen, and hydrogen atoms. Monosaccharides like glucose, fructose, and galactose are types of carbohydrates. An example of a complex carbohydrate is starch. Fats are made up of the same kinds of atoms as carbohydrates. They are made of triglycerides or fatty acid monomers that bind to glycerol.
Protein molecules are made up of nitrogen atoms plus carbon, oxygen, and hydrogen. These nitrogen monomers are essential amino acids needed by the body. They perform functions that are essential in metabolism. They are used for energy and fuel for the body. Antioxidants and phytochemicals are other micronutrients that are essential to the body.
Most of the foods that you consume are made up of several of the classes of nutrients. Some of the nutrients are needed by the body all the time while the others are needed once in awhile. People’s health deteriorates because of the imbalance of nutrients. There can be too much of a nutrient or a deficiency in it.

Answer:
Option A, Absorption
Explanation:
Complete question -
The passage of the end products of digestion into the cells of an organism is an example
a) absorption
b) digestion
c) circulation
d) regulation
Solution -
Nutrient absorption occur in the small intestinal mucosa because it has large surface area as compared to the surface area of stomach. These nutrients are absorbed by the guts so that it is then released into the blood stream. The blood stream carries the nutrient along with it and transport it to the brain, organs and other parts of the body as per their requirement.
Thus, option A is correct
