7) Water evaporating from the surface of a lake moves from the?
The water cycle or the hydrological cycle is the motion of water from the surface of the earth into the atmosphere and is cycled into the ecosystem.
Most of the water on the surface of the earth is recycled by the cyclic mechanism of the sun. The processes of evaporation, condensation, and precipitation are responsible for the cyclic motion of the water on earth. The escaping of water molecules due to the wind and or due to rise in temperatures in the lake move above from the surface after attaining low pressure.Thus the vaporized form of water moves away from the lake.

How do researchers hope to understand healthy aging by the study of proteins?
Answer:
Of course, you could scan their driver’s license or look for signs of facial wrinkles and gray hair. But, as researchers just found in a new study, you also could get pretty close to the answer by doing a blood test.
Woman looking at herself in mirror That may seem surprising. But in a recent study in Nature Medicine, an NIH-funded research team was able to gauge a person’s age quite reliably by analyzing a blood sample for levels of a few hundred proteins. The results offer important new insights into what happens as we age.

Briefly describe why plants produce flowers.
Answer:
The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

The
is the point at which environmental resources limit
population growth.
O A. exponential growth
O B. carrying capacity
O C. population crisis
O D. logistic growth
Answer:
Carrying Capacity
Explanation:
The limits due to environmental resources such as food and mates.
The point at which environmental resources limit population growth is known as the carrying capacity. Therefore, the correct answer is B. carrying capacity.
What is Carrying capacity?Carrying capacity refers to the maximum number of individuals of a given species that a particular environment can support sustainably over time, taking into account the available resources, such as food, water, shelter, and space.
When a population exceeds its carrying capacity, it can lead to resource depletion, environmental degradation, and ultimately, a decline in population size.
Logistic growth is a type of population growth that takes into account the carrying capacity of an environment. It starts with exponential growth and then levels off as the population approaches the carrying capacity.
Population crisis is a term that generally refers to a situation in which a population faces significant challenges, such as food scarcity, disease, or conflict, that threaten its survival.

Which learning process occurs when organisms are able to distinguish between various similar stimuli and respond only to certain ones?
A.
acquisition
B.
discrimination
C.
extinction
D.
generalization
Answer:
b
Explanation:
The learning that process occurs when organisms are able to distinguish between various similar stimuli and respond only to certain ones is discrimination. The correct option is B.
What is stimulus?A stimulus is defined as anything that can cause a physical or behavioral change. Stimuli is the plural of stimulus.
External or internal stimuli can be used. Your body's response to medicine is an example of external stimuli. Internal stimuli include changes in vital signs caused by changes in the body.
Stimulus generalization occurs when a similar stimulus to an already-conditioned stimulus begins to elicit the same response as the original stimulus.
Stimulus discrimination occurs when an organism learns to distinguish the CS from other similar stimuli.
The process by which an organism learns to respond differently to similar stimuli is known as stimulus discrimination.
According to classical conditioning, the organism only exhibits the conditioned response in response to the conditioned stimulus.
Thus, the correct option is B.

single-celled amoebas join to form a multicellular mass that will later reproduce.
Which level of the hierarchy of organization does this mass most
closely represent?
Organ system
Tissue
Organ
Molecule
Answer:
The correct answer is - tissue.
Explanation:
In an unfavorable condition like scarcity of food, individual unicellular organism amoeba makes a formation a multicellular mass by aggregation of the cells that reproduce when conditions become favorable. These aggregation of cells known as slime molds.
These molds are more similar to the tissue structure in the hierarchy of organization of a multicellular organism. The tissue is the organization level that is similar to this mass as it is also formedby the cells joined together to perform a particular function.

what are the two product of the krebs cycle
Answer:
Explanation:
For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced. Each glucose molecule produces two molecules of acetyl CoA, enough for two cycles.
Answer:
[tex]\boxed {\boxed {\sf 2 \ ATP, 10 \ NADH, \ 2 \ FADH_2, \ 4/6\ CO_2 }}[/tex]
Explanation:
The Krebs Cycle is one part of cellular respiration, the process that makes energy/ATP for an organism.
In glycolysis, pyruvic acid is made. After, the molecules are changed to acetyl-CoA.
In the Krebs Cycle, oxaloacetic acid combined with acetyl-CoA form citric acid. Enzymes cause reactions, the NAD molecule gains a hydrogen ion (becomes NADH), and FAD also gains hydrogen ions (becomes FADH₂).
Energy is released, so some ATP can be made. Carbon atoms are released as carbon dioxide (exhaled as a waste product).
So, the Krebs Cycle actually has more than 2 products.
For every 2 pyruvic acid:
2 ATP: energy10 NADH: electron carriers in the electron transport chain2 FADH₂: also electron carrier4 CO₂ (Krebs Cycle) + 2CO₂ (converting pyruvic acid): waste gasIf the offspring of the cross showed incomplete dominance, what would the color of the offspring be?

What is the correct term for microbial action that converts inorganic phosphorous back into organic phosphorus?
The process of _______ refers to the conversion of inorganic phosphorus to organic phosphorus.
Answer:
Mineralization
Explanation:
In biology, mineralization refers to a process where an inorganic substance precipitates in an organic matrix. This may be due to normal biological processes that take place during the life of an organism such as the formation of bones, egg shells, teeth, coral, and other exoskeletons
The process of mineralization is referred to the conversion of inorganic phosphorus to organic phosphorus.
Mineralization is the procedures by which chemicals found in organic matter are decayed or oxidized into forms that plants can use.
The transformation of organic molecules in the soil is driven mainly by its microbiota, which includes fungi and bacteria as well as earthworms.
Mineralization tends to increase the nutrient bioavailability found in decaying organic compounds, most notably nitrogen, phosphorus, and sulfur because they are plentiful.
Carbon mineralization is the transformation of carbon dioxide into a solid mineral, such as carbonate. Whenever these rocks are exposed to carbon dioxide, a chemical reaction occurs.
Thus, the answer is mineralization.

What would happen to the concentrations of Pyruvate, NADH and intermembrane H+ if the ETC stopped working?
Answer:
"Proton decreases" would be the right approach.
Explanation:
The Kreb cycle or system plays a key role throughout a matrix of mitochondria. 3 NADH, 2 FADH2 as well as 1 ATP are synthesized. Whenever the Kreb process has been halted, the acetyl CoA throughout the Kreb cycle has not been used. Pyruvate doesn't at all, disintegrate via acetyl CoA. Therefore in cells, pyruvate accumulates. Unless the Kreb loop is halted, therefore the concentration of NADH and FADH2 declines.Thus, they aren't used for the transportation chain of electrons. This is also why protons have not been discovered to be injected towards intermembrane space.
