The energy required for organisms to respond to the environment comes from.
The energy required for organisms to respond to the environment comes from sun.
How do producer organisms obtain energy?The Sun is our star and it represents the most important source of energy for all organisms in a given ecosystem (both consumers and producers).
Producers are organisms at the bottom of the food pyramid that can synthesize biomass by using light energy from the Sun.
In conclusion, the energy required for organisms to respond to the environment primarily comes from the sun.

Participating in cardiovascular exercise in the target heart rate zone will result in:.
Participating in cardiovascular exercise in the target heart rate zone will result in the reduction of the risk of heart disease, stroke, and diabetes.
What is the target heart rate zone?The target heart rate is typically represented as a percentage of your maximum safe heart rate, typically between 50 and 85 percent.
The highest rate is determined by deducting your age from 220. Therefore, the maximum heart rate for a 50-year-old is 220 minus 50, or 170 beats per minute.
Your ability to complete daily tasks more easily can be increased by increasing your cardiovascular endurance. Additionally, it can lower your risk of developing conditions including diabetes, heart disease, and stroke.

13.04 building muscles explain muscles
Answer:
Muscle is a soft tissue found in both animals and humans. The cells of the muscles comprise protein filaments of actin and myosin that slide past one another, which produces contraction and changes both the length and the shape of the cell.
Muscles function by producing force and motion and are primarily responsible for:
1. Locomotion.
2. Maintaining and changing body posture.
3. Circulation of blood cells throughout the body.
4.Movement of internal organs, such as the contraction of the heart and the movement of food through the digestive system via peristalsis.
There are three types of muscles
•Skeletal or striated muscles
•Cardiac muscles
•Smooth muscles
Based on the muscle action, muscles are further classified into:
•Voluntary muscles
•Involuntary muscles

Answer:
b) The nucleus
Explanation:
The DNA in the nucleus gives instructions which is used to create proteins. Hence, the option (b) is correct answer.
The instructions used to create proteins originate in the nucleus. Therefore, option B is correct.
What is a nucleus?According to genomics, a cell's membrane-enclosed organelle called a nucleus houses the chromosomes. Three main things are the nuclear envelope, nucleolus, and chromatin body.
The nucleus functions as the cell's control center and genetic information store by containing the genome. Only the final phase of gene expression (translation), which takes place in the cytoplasm, is associated with the cytoplasm. DNA replication, transcription, and RNA processing all occur within the nucleus.
DNA is synthesized in the nucleus, it contains information for the formation of proteins. The instructions used to create proteins originate in the nucleus. Therefore, option B is correct.

In which squares should the phrase "Green pods" appear?
O A and D only
OB and E only
O A, C, and D only
O A, B, C, D, and E
The inheritance pattern of pods color in pea plants is complete dominance. H0m0zyg0us dominant and heter0zyg0us plants have green pods. Option C) A, C, and D.
What is complete dominance?When the dominant allele completely masks the recessive allele, we talk about complete dominance.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
When you cross an individual who is h0m0zyg0us dominant with an individual who is h0m0zyg0us recessive, the whole progeny among the first generation -F1- will express the dominant phenotype since they are heter0zyg0us for this trait.
However, if you let individuals from the F1 cross with each other, the second generation -F2- will be composed of individuals expressing the dominant and the recessive phenotypes. This is because some individuals are h0m0zyg0us recessive and can express the recessive trait.
According to this information, and based on the attached flowchart, we can assume that,
Parentals ⇒ A (gray square) and B (white square)F1 ⇒ C (gray square)F2 ⇒ D (gray square) and E (white square)Since the F1 is completely gray, we can assume this color identifies the dominant phenotype (green pods).
The cross was performed between plants with yellow and green pods, so they must be h0m0zyg0us individuals (dominant and recessive) and the whole F1 must be heter0zyg0us for the trait. So,
A ⇒ h0m0zyg0us dominant because it is gray ⇒ green pods
B ⇒ h0m0zyg0us recessive because it is white ⇒ yellow pods
C ⇒ heter0zyg0us because it is gray and the product of A x B ⇒ green pods
Now, the F2 is composed of D and E which represent plants with yellow and green pods. This means that there are h0m0zyg0us recessive individuals, and the recessive trait -yellow pods- can be expressed again among the second generation.
D ⇒ h0m0zyg0us dominant and heter0zyg0us ⇒ green pods (gray square)
E ⇒ h0m0zyg0us recessive ⇒ yellow pods (white square)
Now, the phrase "Green pods" should appear i all gray squares. These are A, C, and D.
Option C is correct. A, C, and D only.

organism that allows it to perform a
biochemical reaction
B. a feature of the organism's body
that helps it survive and reproduce
C. a response from the organism that

Anatomical adaptations involve every change in the organism's external structure. Option B. A feature of the organism's body that helps it survive and reproduce.
What is an anatomical adaptation?Anatomical adaptations are changes in the external structure of the organisms that help them survive and reproduce in a certain environment.
These adaptations allow the organisms
to camouflage if necessary (to scape from a predator or to hunt their prey, for instance), to protect themselves by imitating dangerous species' colors and shapes, to develop special structures needed to feed and move in that specific environment.
There are other two types of adaptations apart from anatomical ones. These are physiological and behavioral adaptations.
Options
A. a system present within the organism that allows it to perform a biochemical reaction ⇒ This is a physiological adaptation
B. a feature of the organism's body that helps it survive and reproduce ⇒ This is an anatomical adaptation
C. a response from the organism that changes it's behavior to help it survive and reproduce ⇒ This is a behavioral adaptation
The correct option is B. a feature of the organism's body that helps it survive and reproduce

How does the body obtain more glucose, if it is needed for cell respiration?
Through the process of cellular respiration, the energy in food is changed into energy that can be used by the body's cells. Initially, the sugars in the food you eat are digested into the simple sugar glucose, a . The varying glucose concentration affects the rate of cellular respiration as all living cells require both glucose and oxygen for their proper functioning. If the cell has a low level of glucose, then it cannot produce the energy -ATP molecules.
monosaccharide means any of the class of sugars (e.g., glucose) that cannot be hydrolyzed to give a simpler sugar.

From the illustration, it can be said that the age of the rock layer is the same in the four locations of index fossil 1.
Age of fossilIt is a measure of how long a material has been fossilized.
Thus, if a rock layer contains a fossil and another similar rock layer does not have the fossil, one can conclude that the ages of the rock layers are different.
Only index fossil 1 is found in all the four locations as shown in the image. Hence, one can as well infer that the rock layers in all these four locations are of the same age.

When a protein denatures, which type of bonding is effected?
Answer:
When a protein is denatured, secondary and tertiary structures are altered but the peptide bonds of the primary structure between the amino acids are left intact. Since all structural levels of the protein determine its function, the protein can no longer perform its function once it has been denatured.A protein becomes denatured when its normal shape gets deformed because some of the hydrogen bonds are broken. Weak hydrogen bonds break when too much heat is applied or when they are exposed to an acid (like citric acid from lemon juice).

Answer: Auxin is a plant growth hormone that aids in the regulation of shoot development. However, when the amount of sunshine fluctuates, auxin is broken down on the stem's sunny side.
