Explanation:
Mary wanted to know if seeds needed water to start growing or if any kind of liquid would work. Mary set up several experiments to find out. She used radish seeds, paper towels, plastic bags, and different kinds of liquid in her experiment. Mary put three seeds into each bag. She then used 30mL of liquid to wet a paper towel and put a different paper towel in each bag. Mary put all of the bags on the same table next to a window so that they could each get the same amount of light. She waited three days and then checked her plants.

Answer:
independent variable: 30mL of liquid to wet a paper towel
dependent variable: how much the plants grow if at all.
control: they all received the same amount of light, that or the paper towels are the same.
experimental group: It's not stated that she did indeed use water, but there is a need for a control group, if so, then it's the other 2 groups that didn't use water, also because I can't think of anything else.
control group: The groups that used water rather than the other 2 plants.

Which of the following best describes an antigen?
B. A recognition molecule on the surface of the cells.
What is antigen?An antigen is a substance that is capable of triggering an immune response in the body. It is typically a foreign substance, such as a pathogen (e.g. a virus or bacterium), a toxin, or a non-infectious particle (e.g. pollen or dust), that is recognized by the immune system as being foreign and potentially harmful.
When an antigen enters the body, it is recognized by immune cells called B cells and T cells, which produce proteins called antibodies to help neutralize and remove the antigen. The antigen-antibody interaction is a key part of the body's immune response and helps to protect us against infectious diseases.
Antigens can also be present on the surface of our own cells, such as cancer cells or transplanted organs, and can trigger an immune response if they are recognized as foreign by the immune system.
Overall, antigens are important components of the body's immune system and play a critical role in protecting us against infectious diseases and other threats.

How does your body respond to an increase in the need for energy----why would you need more energy?
Answer:
Exercise can boost energy levels by raising energy-promoting neurotransmitters in the brain, such as dopamine, norepinephrine, and serotonin, which is why you feel so good after a workout. Exercise also makes muscles stronger and more efficient, so they need less energy, and therefore conserve ATP.

Give an example of an adaptation
An adaptation is any characteristic that helps a plant or animal survive in its environment. A penguin's feathers are an adaptation. For example, animals that live in cold places have adaptations to keep them warm. Plants that live in dry areas have adaptations to help them conserve water.
Answer:
Adapting to a new environment is an example of adaptation.
Explanation:
Adaptation means to be able to adjust to something new.
The greatest number of relationships between the
organisms in an ecosystem is best shown in
A. a food chain
B. an energy pyramid
C. a food web
D. an ecological succession diagram
The greatest number of relationships between the organisms in an ecosystem is best shown in a food web. Thus, the correct option is C.
What is a Food web?A food web consists of all the food chains which are present in a single ecosystem. Each of the living thing in an ecosystem is a part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem.
For example- A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. It is a food web that shows the many different paths plants and animals are connected.
Therefore, the correct option is C.

Environmental degradation must be reduced, so by the baseline data of the world's ecosystem must be researched.
What is the world's ecosystem?Ecosystem defines the interaction between living (biotic) components and nonliving (abiotic) components. A living system depends on nonliving factors around them.
Temperature, soil, and light are all components that are necessary for the living system to reproduce and survive. Plants can not do photosynthesis without light and also get minerals and water from the soil.
We need to understand the baseline of the world's ecosystem, so climate-changing conditions can be reduced. Global warming is a critical condition for the ecosystem and can be reduced by research.
Therefore baseline data on the world's ecosystem must be researched to improve environmental conditions.

how can food handlers reduce bacteria to safe levels when preparing vegetables
These can be done by washing of the vegetables, good kitchen Hygiene and proper storage.
Vegetables are perishables, with some quantity of stored water and therefore they harbor bacteria.
Hands should be washed before handling to prevent contamination.Thorough washing should be done under running water to remove the bacteria. The water current sweeps away the bacteria.Further washing of the vegetables in the warm water with 2% saline solution is needed to kill some other bacteria and pesticides resistant to cold water. This is also remove pesticides residue on the leave surfaces.The vegetables should be stored in the refrigerator to slow down the activity of the bacteria prior to cooking or before eating.for more on handling of handling of vegetables to remove bacteria; https://brainly.com/question/4179837

if you have been to a beach for a whole day, then you have seen tides roll in and out. What causes
Earth's high tides?
Answer:
The Moon
Explanation:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Answer:
it's caused by the gravitational forces from the moon.

can anybody describe why it rains? Include the words that scientists use
when talking about how water changes from liquid to gas and back to liquid
again
In a cloud, water droplets condense onto one another, causing the droplets to get bigger and increase. When these droplets heavy enough, they fall to Earth as rain droplets. That is when we feel and see the rain. Water vapor turns into clouds when it cools and then condenses,or when it turns back into liquid water or ice.
