Explanation:
Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.
All organism are composed of one or more cells
The cell is the structural and functional unit of lif
It is a de novo structure, that means it COULD arise from non living thing which was incorrect.
What do you call these 2 groups of ribs?
In the first image, those are fake ribs that are attached to the sternum through the costal cartilage
in the second image are real ribs since they are directly attached to the sternum
favorable variatons are determined by environmental conditions and pressures
is it natural selection, artificial selection, or both ?
-How do you think andioxidants can help cells perform their functions? -Why do plants have more antioxidants than humans? -Do you think this can be related to structure? How? - How can you relate diet to cell structure and function?
Answer:
Antioxidants help cells perform their functions against something called free radicals. Free radicals are molecules that happen to be produced when your body breaks down food and/or when you inhale or are exposed to tobacco products. These molecules play a role in leading to diseases such as; Heart disease and cancer. When plants synthesize, they collect many non-enzymatic Antioxidants like ascorbic acid and phenolic. Since plants have many more sites of ROS generation, Therefore, they could evolve more efficient non-enzymatic Antioxidant systems than humans because of their high intake and exposure to oxygen. (answer yourself about the structure in your own words using the information I gave you). Diet relates to both the function, structure and health of your cells. Having a balanced diet helps your cells to happily work and produce energy for your daily use. A balanced diet supplies your body with nutrients so it can work effectively. Without balanced nutrition, your body is way more prone to disease, fatigue, low performance and infections.

Hairline shape is an inherited trait. The widow's peak allele is dominant over the straight hairline allele. If both parents have a widow's peak, can they have a child with a straight hairline? Why or why not?
They can have a child with straight hairline even though they posses the dominant phenotype only if the genotype is heterozygous.
Answer:
They can have a child with straight hairline even though they posses the dominant phenotype only if the genotype is heterozygous.

You do need to switch your answers.
Explanation:
In animal cells, the cell membrane pinches together in the middle of the cell to cut in half or divide the cytoplasm.
In plant cells, the cell wall of a plant cell is rigid, it does not pinch in like the more flexible cell membrane in animal cells. It has a structure called a cell plate that forms across the middle of the cell.

The electron Transport Chain produces how many ATP molecules?
Answer:
34 ATP molecules
Explanation:
This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.
Hope this helps!!!!!
Answer:
34
Explanation:
The Electron Transport Chain produces the most amount of ATP molecules (compared to glycolysis and Krebs Cycle)
Explain the process of chemiosmosis (the chemical gradient used in ATP synthase to produce ATP)
The light reactions of photosynthesis generate ATP by the action of chemiosmosis. These protons then flow down their electrochemical potential gradient through an enzyme called ATP-synthase, creating ATP by the phosphorylation of ADP to ATP.

These systems are important in fighting off infection. the endocrine system and the immune system the immune system and the cardiovascular system the integumentary system and the respiratory system the immune system and the lymphatic system
Answer:
The immune system and the lymphatic system
Explanation:
The lymphatic system is apart of the immune system and is very important because it basically helps the general functioning of the immune system and without it the immune system wouldn't work.
Answer:
The lymphatic system and the immune system
Explanation:
The endocrine system consists of glands that produce hormones to control your body's activities. These can include the pituitary, adrenal, ovaries, testes, etc., which do not relate battling off an infection. The cardiovascular system is an equally important system that is dedicated to circulating your blood through various types of blood vessels and transporting gases, hormones, etc., which does not help at all with battling off an infection, and in fact can allow it to spread and worsen. The integumentary system, consisting of skin, hair, and nails, is meant to serve as a defense layer and provide protection, but not to stop an infection, which leaves us with the last answer, the immune system and the lymphatic system that we can, therefore, determine as the correct answer. For further proof, the lymphatic and immune system do actually work together to battle pathogens, viruses, and infections, which is what the question is asking about.
Hope this helped! :]
Which of the following best illustrates homeostasis? (3 points)
O All organs in the human body are composed of the same four kinds of tissues.
O Cells use various forms of transport to move materials through the cell membrane.
O When CO2 levels in the blood Increase, the body responds by breathing faster to release CO2.
O When you touch a hot stove, you instantly pull back your hand before your brain processes the pain.
When CO2 levels in the blood Increase, the body responds by breathing faster to release CO2, best illustrates homeostasis
What is homeostasis ?Homeostasis is the stage where the internal body state is stable, chemical and physical conditions maintained by living systems.
Homeostasis is crucial for the survival of organisms, seen as a resistance to changes in the external environment.
homeostasis is a nothing but a self-regulating process that regulates internal variables necessary to sustain life.
The regulation of homeostasis depends on three mechanisms such as Effector, Receptor, Control Center.
