What do you think? Are polar bears doomed to go extinct or do you think they will survive?
Answer:
Polar bears will go extinct by the end of the 21st century.
Explanation:
Polar bears live at the North Pole. Due to global warming, the ice at the poles is melting at an alarming rate. Soon there won't be any glaciers. Without the ice Polar bears will lose their home. The climate on Earth is becoming warmer day by day. So even if the Polar bears survive they will not be able to adapt to the warmer climate. Thus leading to their extinction.

The features of alveoli for the efficient exchange of gases.
A. Thin wall, moist layer and less blood vessels
B Thin wall, moist layer and more blood vessels
C. Thick wall, moist layer and more blood vessels
Explanation:
The alveoli are lined with mucus and are surrounded by a network of blood capillaries. They have very thin walls for gases to be absorbed through. An individual air sac is called an alveolus. The layer of moisture in the alveoli allows gases to dissolve so that they can diffuse quickly.

The cells that make up lungs and the cells that make up kidneys have different genes, causing lungs and kidneys to look different.
All cells of an organism have the same genes, but different genes are activated within different cells.
When cells and tissues differentiate, they delete the genes they do not need.
All cells have the same genes, and all of a cell's genes are active at the same time.

2. If the perimeter of a triangle is 31 ft and two of the side lengths are 15 ft and 10 ft, what is the length of the third side?
Answer: 6ft
Explanation:
Perimeter is just adding the side lengths together so...
31-15-10=x
6=x
so the answer is 6 ft

A fetus possesses a mutation that causes the diencephalon region of the developing brain to cease growing. Which structures in the mature brain will be missing/abnormal if the fetus survives to birth and childhood
Hypothalamus, pineal gland, and thalamus. Sensory abnormalities, visual-field deficiencies, and alterations in behaviour are all potential consequences of thalamic injury.
Thalamus, hypothalamus, subthalamus, and epithalamus are the four principal diencephalon subdivisions. Recognizing sensory stimuli and relaying sensory impulses to the cerebral cortex (apart from olfaction) are the main duties of the thalamus, which is the brain's biggest division.
One of the primary vesicles that create the brain during embryogenesis is the diencephalon. One of the three main germ layers, the ectoderm, is responsible for forming a neural tube during the third week of development.
Here are the structures that make up the diencephalon:
posterior pituitary epithalamus, thalamus, and hypothalamus

The following RNA strand was produced: 5 AUG GCG UUU 3 Which of the following DNA strands could have been the template for this RNA? Choose 1 answer: A 3 TAC CGC AAA 5' 3' CGT TAT GGG 5' 3' AUG GCG UUU 5' 3' UAC CGC AAA 5
Answer:
A
Explanation:
Each nucleotide is appropriately paired according to the A-U/T-A and C-G pairing rules, so these are complementary strands.
The DNA strand that could have been the template for RNA 5' AUG GCG UUU 3' is 3' TAC CGC AAA 5'.Thus, the correct option is A.
What is a Template strand?A template strand may be defined as the DNA sequence that can duplicate itself during the process of mRNA synthesis. During this process, the cell utilizes a non-coding/antisense DNA sequence as a template to construct mRNA.
The production of the mRNA strand is done with the help of complementary base pairing with that of the template strand. In this process, A is bound to T and vice versa, while C is bound to G and vice versa.
In mRNA, the Thymine (T) is replaced by Uracil (U). According to Chargaff's rule, the amount of ADENINE is equal to THYMINE, while the amount of GUANINE is equal to CYTOSINE.
Therefore, it is well described above.

Which statement regarding the distances between the planets in our solar system is accurate?
o A. Equal distance separates the inner planets.
B. Inner planets are farther from one another than are outer planets.
C. Equal distance separates the outer planets.
D. Outer planets are farther from one another than are inner planets.
The correct statement is that the outer planets are further from one another than the inner planets. So the correct option is D.
What are the outer planets?There are eight planets in our solar system that are classified according to their distance from the sun.
The planets closest in distance to the sun are called the inner planets. The first four planets of the solar system are classified as the inner planets. These are Mercury, Venus, Earth, and Mars.
The rest of the four planets of the solar system are farther in distance from the sun. They are called the outer planets. These are Jupiter, Saturn, Uranus, and Neptune.
The outer planets are much bigger than the inner planets and make up for 99 percent of the mass of all celestial bodies that revolve around the sun.
The outer planets are mainly composed of gases and are called gas giants or jovian planets. The distance of outer planets between one another is much more than the distance of inner planets between one another.
Therefore, the correct option is D.

An examination of racial classifications from around the world indicates that Group of answer choices the best racial classifications are based solely on phenotypic traits. all cultures classify races similarly. the best racial classifications are based solely on genotype. the classification of racial types is an arbitrary, culturally specific process. the best racial classifications are based on both genotype and phenotype.
Answer:
the classification of racial types is an arbitrary, culturally specific process.
Explanation:
Racism can be defined as an act, practice or policy by an individual, group of people or institutions which typically involves promoting the ideas and belief that a race is superior in comparison with another. Thus, it simply means the believe that a particular race has dominance over another (an inferior race).
An examination of the classifications of races from around the world indicates that the classification of racial types such as Africans, Americans, Indians, Asians, Black-Americans, Hispanics, etc., is typically based on individual perception, not objective and an impulsive (arbitrary), culturally inclined or specific process.
This ultimately implies that, the classification of racial types is considered not to be based on any form of objective distinction but may be defined by a person's culture.
A culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

Why is it important to protect networks of ecosystems and habitats? Provide an example of a species in Alberta that would benefit from such protection and state why
Answer:
To maintain stability.
Explanation:
It is important to protect networks of ecosystems and habitats in order to get healthy and stable environment because the environment depends on ecosystems and habitats. If there is no ecosystem or habitat is destroyed then the whole ecosystem will greatly damaged that leads to the extinction of many animals that maintain stability in the environment. Swift fox (Vulpes velox) and Bison (Bison bison athabascae) are the two species that can be protected by protecting habitat and ecosystem.

During a baseball game, a hitter strikes the ball with a bat. When this happens, the ball and the bat exert a
force on each other. Why does the ball accelerate away from the bat more than the bat accelerates away from
the ball?
Answer:
The ball has greater velocity before the collision, so the force affects the ball more than it affects the bat. The ball has less mass, so the equal force on the ball and the bat causes greater acceleration of the ball. The bat exerts more force than the ball because the batter is exerting a force on the bat as it hits the ball
