Explain the different types of bonds that occur in molecules.
Answer:
Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

Explain how the lungs are adapted for diffusion of gases
Answer:
well u know how we breath air in its the same as gas so your lungs are used to narcotics like smoking and vaping and stuff
Explanation:
Answer: Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Explanation: The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.

This protein is also needs _____________ factors, which are a group of proteins which regulate transcription of genes. When lactose IS present, the ________________ protein falls off and __________________ binds to the promotor, initiating transcription.
Answer:

Answer:
C
Explanation:
A. is incorrect because the cell displayed is an animal cell not a plant cell, so it cannot photosynthesize. The organelle shown is actually the ER.
B. is incorrect because the structure labelled is the nucleus, not a vacuole. Vacuoles store substances like waste, not DNA.
C. Is correct because the pickle-like organelle is the Mitochondria, also known as the powerhouse of the cell due to cellular respiration taking place there.
D. Is incorrect because the cellular membrane of the animal cell is not rigid like the cell wall of the plant cell, instead it is more semi-permeable.

What are the target cells for the human Growth Hormone?
Answer:
Once released into the circulation, GH binds and activates the cell-surface GHR, as well as the related prolactin receptor in target tissues such as liver, muscle, bone, and adipose tissue
Explanation:
Direct effects are the result of growth hormone binding its receptor on target cells. Fat cells (adipocytes), for example, have growth hormone receptors, and growth hormone stimulates them to break down triglyceride and supresses their ability to take up and accumulate circulating lipids.
Answer:liver, muscle, bone, and adipose tissue I think
Explanation:
Describe evolution in your own words.
Evolution is the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.
EvolutionEvolution can be defined as the change in the characteristics of a species over several generations. Evolution occurs when evolutionary processes such as natural selection and genetic drift act on this variation, resulting in certain characteristics becoming more common or rare within a population.

Which feature of viruses prevents them from being classified into a kingdom?
a. They are not living organisms.
b. They are not contagious.
c. They are not virulent.
d. They are not pathogens.
Answer:
A
Explanation:
Were viruses ever alive? Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Answer: A
