Hormones in the soil help fruits develop and ripen.
Hormones in the soil allow seeds to germinate.
Hormones in the plant allow seeds to germinate.
Hormones in the plant help fruits develop and ripen.
Answer:
Hormones in the plant help fruits develop and ripen.
Explanation:
The growth of plants is regulated by "plant hormones." There are primarily 9 plant hormones and these are: ethylene, salicylic acid, cytokinins, auxin, abscisic acid, gibberellins, strigolactones, nitrous oxide and brassinosteroids. Fruit-ripening is highly associated with "ethylene." These hormones also affect the yield production.
The image above shows how the two fruits became bigger from left to right. This portrays the fruits' ripening.

(15 points) One of the accepted scientific theories describing the origin of life on Earth is known as chemical evolution. According to this theory, which of the following events would need to occur first for life to evolve?
Answer:
Synthesis of organic molecules
Explanation:
because i said so
According to chemical evolution, synthesis of organic molecules would need to occur first for life to evolve. Option C is correct.
What is chemical evolution?The theory of modern chemical evolution is based on postulate that, on primitive earth, the most complex molecular system, which lead to formation of first functioning cell, arise from mixture of simpler chemicals.
Chemical evolution of organic chemicals was preceded by the and physical chemical conditions of the primitive Earth. A two step process is proposed by scientists to explain life origin :
Formation of biomolecules, which is combination of organic molecules and,Formation of living organisms by self organization of biomolecules.Therefore, concept of biogenesis must be placed for evolution of in chemical evolution. Thus, option C is correct.

If a 4 kg object is moving 5 m/s, how much kinetic energy does it have?
Answer:
K.E = 50 J
Explanation:
Given data:
Mass of object = 4 Kg
Speed of object = 5 m/s
K.E = ?
Solution:
Formula:
K.E = 1/2mv²
by putting values,
K.E = 1/2 × 4 Kg × ( 5m/s)²
K.E = 1/2 × 4 Kg ×25 m²/s²
K.E = 50 J (Kgm²/s² = J)

A student measures his pulse rate while he is watching television and records it. Next,
he walks to a friend's house nearby and when he arrives, measures and records his
pulse rate again. He and his friend then decide to run to the mall a few blocks away. On
arriving at the mall, the student measures and records his pulse rate once again.
Finally, after sitting and talking for a half hour, the student measures and records his
pulse rate for the last time.
Which graph below best illustrates the expected changes in his pulse rate according to
the activities described above?
Key:Activity
A = after watching
television
B = after walking to a
friend's house
C = after running to
the mall
D = after sitting and
talking
Children who spend too much time on screens may develop obesity, sleep issues, chronic neck and back pain, depression, anxiety, and poorer academic performance. Thus option A is correct.
What effect on pulse rate after watching television?A typical normal resting heart rate ranges from 60 to 100 beats per minute (bpm). That is therefore probably what your resting heart rate is if you check it while you're sitting and watching TV or lying down and reading a book.
Additionally, watching more TV was linked to an increased risk of diabetes and hypertension. Compared to those who watched TV for 7 hours or less each week, those in the high TV-watching group had a 68 percent higher risk of hypertension and a 50 percent higher risk of diabetes.
Therefore, Longer television watching is linked to a faster heart rate. The current study showed that watching television for a longer period of time was linked to a slightly elevated heart rate.

The statements that best describe the first stage of cellular respiration are as follows:
The stage happens in the cytoplasm. Glucose is broken down.Energy is released.Thus, the correct options for this question are A, D, and E.
What is Cellular respiration?Cellular respiration may be defined as a process through which the molecules of glucose are broken down into carbon dioxide and water with the liberation of energy in the presence of oxygen. This process takes place in the cytoplasm of the cell.
During the process of cellular respiration, a molecule of glucose is broken down into two molecules of pyruvate (pyruvic acid). This demonstrates the first stage of cellular respiration which is known as glycolysis.
Therefore, the correct options for this question are A, D, and E.

short term energy
insulation
Short term energy is the function of Lipids. So, the correct option is (D).
What are Lipids?Lipids are defined as naturally occurring molecules which include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, phospholipids, and others. The main functions of lipids include energy storage, signaling, and serving as structural components of cell membranes.
Biological lipids are not large macromolecular polymers such as proteins, nucleic acids and polysaccharides that are formed by the chemical linkage of many smaller constituent molecules. Many of these molecular building blocks are similar or identical in structure.
These lipids are classified into a few major groups such as fatty acids, fatty acid derivatives, cholesterol and its derivatives, and lipoproteins.

An organic compound formed is the dark reaction of photosynthesis is
a. glucose
b. chlorophyll
C. Oxygen
d. water
An organic compound formed is the dark reaction of photosynthesis is glucose.
The reduction of carbon happens in the stroma of chloroplasts through a series of reactions known as the Calvin cycle, also known as the dark phase of photosynthesis.
The NADPH and ATP synthesized in the photosystems are used at this stage and stored in a more stable molecule, glucose.At each complete turn of the cycle, a carbon dioxide molecule enters the cycle and is reduced, presenting regeneration of a RuBP molecule.Six turns of the cycle, with the introduction of six carbon atoms, are necessary to produce a six-carbon sugar, such as glucose.Therefore, we can conclude that an organic compound formed is the dark reaction of photosynthesis is glucose.
