Answer:
mutations
on edge
It was Charles Darwin who called the birds seen on the Galapagos islands as the finches. These birds show a remarkable diversification in their beak based on their chief food.
What are Darwin's Finches?Charles Darwin observed a group of small sparrow like black birds with strong, short beaks which are known today as Darwin's finches. These finches varied on different islands, but they were closely related to one another.
These finches evolved from a common ancestors to have different beaks well suited for different types of food they feed on. Generally long and pointed beaks are suitable for seed and cactus feeders. Even some short beaked finches tear up the base of the cactus and feed on its pulp.
The slender and sharp beaks are common in insect eating finches. The process by which they successfully evolved and radiated to different habitats is called the adaptive radiation.

A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: Osmosis, because energy is being used to move molecules with the concentration gradient. Active transport, because energy is being used to move molecules against the concentration gradient. Facilitated diffusion, because energy is being used to move molecules with the concentration gradient
Answer:
Active transport, because energy is being used to move molecules against the concentration gradient.
Explanation:
This picture shows active transport. That just means that energy is being used (in this case, ATP) to move molecules against their gradient (meaning, from low to high concentration). Molecules "naturally" diffuse from high-->low concentration, so to move in the opposite direction requires energy input. You can tell this because there are only 2 molecules on the top side of the membrane, but on the bottom side there are 13.
Why not A: This is not necessarily water, as in osmosis, and it's not going with the gradient.
Why not C: This is not facilitated diffusion, because molecules are going against, not with, their concentration gradient.
The description that best identifies this type of cellular transport is: Active transport, because energy is being used to move molecules against the concentration gradient.
WHAT IS ACTIVE TRANSPORT:Active transport is a type of transport that requires the input of energy in form of ATP. This is because the movement of molecules is against a concentration gradient. According to the diagram in this question, molecules are being moved into the cell with an input of ATP (energy).Therefore, the description that best identifies this type of cellular transport is: Active transport, because energy is being used to move molecules against the concentration gradient.

Vaccines have been subjected to quite a bit of controversy in recent years. Currently, the Centers for Disease Control and Prevention (CDC) recommend that healthy people receive a flu vaccine every year. What are your current perceptions of the flu vaccine? Do you think these recommendations are appropriate? Explain your reasoning.
Answer:
There are many reasons to get an influenza (flu) vaccine each year.
Flu vaccination can keep you from getting sick with flu.
Flu vaccination can reduce the risk of flu-associated hospitalization for children, working age adults, and older adults.
Flu vaccination is an important preventive tool for people with chronic health conditions.
Flu vaccination helps protect women during and after pregnancy.
Flu vaccine can be life-saving in children.
Flu vaccination has been shown in several studies to reduce severity of illness in people who get vaccinated but still get sick.
Getting vaccinated yourself may also protect people around you, including those who are more vulnerable to serious flu illness, like babies and young children, older people, and people with certain chronic health conditions.
Explanation:
Influenza is a potentially serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and influenza infection can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. An annual seasonal flu vaccine is the best way to help protect against flu. Vaccination has been shown to have many benefits including reducing the risk of flu illnesses, hospitalizations and even the risk of flu-related death in children.
Flu vaccines helps to reduce the risk of flu-associated illness. And the recommendations made by CDC that healthy people receive a flu vaccine every year is appropriate.
What is flu?"Also called influenza is a viral infection which can be deadly in high risk groups."Flu symptoms include- fever, cough, cold, fatigue, headaches and muscle pain.It causes asthma, pneumonia and chronic diseases.What is flu vaccines?"These are the vaccines that protect against infection by influenza viruses."What is CDC?"It is the National public health agency of the United States."Hence, in order to reduce the disease caused by flu, it is recommended to receive a vaccine.

Runoff is a step in the water cycle where the water combines with pollutants on Earth's surface. Therefore, the correct statement is option D.
Plants take up water from the ground through transpiration process. Therefore, the correct statement is option A.
What is runoff water cycle?During the water cycle, when water combines with the pollutants present on the surface of the earth, the process is called runoff. During runoff, water comes from the melting snow or other resources and moves towards the surface of the land, thereby, carrying pollutants and other chemicals along with it from urban or agricultural areas and ultimately carried the pollutants into streams and rivers, and eventually into lakes and oceans.
Therefore, runoff water causes various harmful effects on human health as well as aquatic life. Therefore, runoff water should be properly treated to prevent pollution.
Plants take up water from the ground through a process called transpiration where water present in the soil gets absorbed by the roots of the plants and then further transported to the top of the plant through the stem and also into the leaves.
Therefore, runoff is a step in the water cycle where the water combines with pollutants on Earth's surface and plants take up water from the ground through transpiration process.

Answer:
D. Aphanite
Explanation:
A.P.E.X
An invasive igneous body is aphanite. Thus, the correct option is D.
What are Aphanite rocks?
Aphanite's are igneous rocks that were formed by rapid cooling in a volcanic or hypabyssal setting and are so finely grained that their individual mineral crystals cannot be seen with the unaided eye.
Very fine-grained, crystalline fabrics called aphanitic minerals are created when a magma solidifies in reaction to an exceptionally rapid loss of heat and dissolved gases. They are characterized by grains that are too small to be recognized without a petrological microscope.
Large crystals are known to be present in certain specific igneous rocks. The crystals in this type of rock are approximately the same size. Compared to aphanitic rock, which is known to have rocks with finer grain sizes.

Answer:
d
Explanation:
It leads to a process called as eutrophication in which the aquatic plants grow regularly over the water surface and the living beings living inside the water gets diminished because of the lack of nutrients and the various substances required for the growth.
What is water sterilization ?It is the process in which the harmful substances and contaminants are removed outside the water source such that the water can be removed out from water resources such that they can be made appropriate for drinking.
An overabundance of various nutrient primarily nitrogen along with phosphorus in water begins a process known as eutrophication. The process hammers the growth of other lives present on the sources.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green
algae-living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its
photosynthetic activity from Elysia chlorotica, the sea slug that's considered to be a photosynthesizing animal?
CA In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.
B. In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only
during the immature juvenile stage of the slugs life cycle.
OC Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from
algae into its cells.
D. In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a
photosynthesizing organism only when it requires food.
Answer:
The correct answer is option C. Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
