The photo shows a liger. Its father is a male lion, and its mother is a female tiger.

A. Male lions and female tigers can produce offspring.
B. Male ligers cannot produce offspring with female ligers.
C. Male and female tigers cannot grow as large as ligers.
D. Female ligers can produce offspring with male lions or tigers.
Answers
Answer:
A.
Explanation:
Because it makes sense that you NEED a Male Lion and a Female Tiger to produce a Liger. That's the only possible way and I'm 100% sure this answer is correct :)
Male lions and female tigers can produce offspring. Thus the correct option is A.
What is liger?The offspring of a lion and a tigress is called a liger.
Although they rarely meet in the wild, lions and tigers are still so closely related that they are able to interbreed, and in captivity they occasionally do. But successful interbreeding is the key, and the hybrid offspring are usually sterile and short-lived.

How does passive transport come into play in oxygen's journey through our body?
Answers
In the alveoli of the lungs, oxygen frequently diffuses from the air into the erythrocytes and blood plasma.
What is passive transport?Diffusion is a form of passive transport where molecules migrate from a high concentration to a low concentration, if you didn't know. Therefore, it follows that the oxygen content of the air must be higher than that of the blood.
Passive membrane transport methods are the most direct. Passive transport is a phenomenon that happens naturally and doesn't require the cell to use energy to move.
Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration.
Therefore, Passive transport is a term that refers to both osmosis and diffusion. They don't need any power.

Why do the prevailing winds blow from west to east in the Northern Hemisphere?
Answers
Answer:
Low pressure spins counterclockwise, causing weather systems to move from west to east in the Northern Hemisphere.
This is due to lower air pressure further North America than in the tropics. Since low-pressure systems spin counterclockwise, winds move from the west to the east.
Prevailing weather results from expansive convection currents formed by the temperature differences on the surface of the earth as latitude increases. The Coriolis effect adds the twist.
I got this from a few sites so use this information as you want and be careful <3
The prevailing winds in the Northern Hemisphere blow from west to east because of the Coriolis effect. The Coriolis effect is a force that deflects moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is due to the Earth's rotation.
As the Earth rotates, it drags the atmosphere along with it. However, the atmosphere is not a solid object, so it does not rotate at the same speed as the Earth. The atmosphere rotates more slowly at the equator than it does at the poles. This difference in rotation speed creates a pressure gradient, with higher pressure at the poles and lower pressure at the equator.
The pressure gradient force causes air to flow from high pressure to low pressure. However, the Coriolis effect deflects this airflow to the right in the Northern Hemisphere. This results in prevailing winds that blow from west to east.
The prevailing winds in the Northern Hemisphere are called the westerlies. The westerlies are strongest in the mid-latitudes, between 30 and 60 degrees north. They are responsible for bringing warm, moist air from the tropics to the cooler regions of the Northern Hemisphere.
Therefore, The prevailing winds in the Northern Hemisphere blow from west to east because of the Coriolis effect.

Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks.
(PLEASE HELPPPP 90 POINTS!!)
Which best describes the next step in the formation of metamorphic rocks?
Buried rocks melt deep within the mantle.
Lava melts underlying rocks, which crystallize into new minerals.
Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.
Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.
Answers
The correct answer is B. When buried rocks are forced toward the mantle, they undergo extreme heating and pressure, which can cause them to melt. This molten rock is known as magma, which then crystallizes as new minerals as the magma cools and solidifies. This process is known as metamorphosis and is the second step in the formation of metamorphic rocks.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds, evolving long necks has enabled giraffes to feed on leaves that others can't reach, giving them a competitive advantage.

Option C. Cloning because offspring that are exact copies are produced.
This can be explained by:
Cloning is a mode of reproduction in which the replica of the parent is produced as offspring.The genetic content of the offspring is the same as that of the parent.

What type of response occurs when you watch someone eating a lemon and your face puckers?
external response
sour response
internal response
lemon response
Answers
Answer:
The type of response that occurs when you watch someone eating a lemon and your face puckers is an external response. An external response is a physical reaction that is visible to others and occurs in response to a stimulus, in this case, the sight of someone eating a lemon. It is also sometimes called a behavioral response.
An internal response, on the other hand, is a response that occurs inside the body and is not visible to others. For example, when you eat a lemon, you may experience an internal response such as an increased production of saliva in your mouth or a sour taste in your mouth.
A sour response is a type of internal response that refers specifically to the taste of something that is sour, such as a lemon.
A lemon response is not a commonly used term in psychology or physiology. It could refer to any type of response that is related to lemons, such as the external response of puckering your face or the internal response of experiencing a sour taste.

Air travels through the following structures on its path to the alveoli (the site of gas exchange): nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles.
What is breathing?The trachea (windpipe), which is further separated into bronchial tubes, receives it from there. Bronchioles are another division of the bronchial tube, the little alveoli structure is where the bronchioles eventually come to a stop.
Through our noses, we breathe air into our bodies, after then, it moves via the larynx, pharynx, and nasal cavity before entering the windpipe, also known as the trachea.
Therefore, air enters both lungs through bronchi that branch off of the trachea.
