Answer:
It is C
Explanation:
I had this on my test last week
The answer is guard cells.
Guard cells are cells surrounding each stoma. They help regulate the rate of transpiration by opening and closing the stomata. They are specialized cells in the epidermis of leaves, stems and other organs that are used to control gas exchange. They are produced in pairs with a gap between them that forms a stomatal pore (stoma).
Answer
At week 5-6 of gestation, the baby’s heart starts beating.
Explanation
Fertilization occurs in week 3 followed by implantation in week 4.In week 5 the levels of hormones increases with formation of the baby’s heart and circulation system. In week 6, the neutral tube closes followed by development of structures necessary to form eyes and ears. The head of the baby develops at week 7 followed by nose in week 8 and toes in week 9.
Answer: <u>Option B; It traps light energy and converts it into chemical energy.
</u>
This substance is chlorophyll. It is a pigment present in leaves of all plants. It absorbs light energy and provides it to carry out the process of photosynthesis. Light energy is converted into chemical energy, in form of NADPH and ATP, which can be used by plants for photosynthesis.
This pigment is present only in plants, so option A is incorrect.
This pigment only absorbs and transfers energy to other molecules, and is not associated with carbon dioxide directly, so option C and D are also incorrect.
Answer:
Chemical Fertilizers
C. Algal blooms followed by eutrophication is the correct one
Stockyard Runoff
Correct D. Increased biological oxygen demand/decreased dissolved oxygen
Soil disturbance
Correct A. Erosion, flooding; clogged shipping channels and harbors
Pesticides
Correct B. Reproductive failure, poisoning, and/or death (pollinators, pets, livestock, predators, children)
Explanation:
For industrial agriculture to be effective and productive today, we have to take into account many factors so our practices function in a good way. When it comes to chemical fertilizers, it is NOT a risk the Increased biological oxygen demand/decreased dissolved oxygen
, the correct risk is algal blooms followed by eutrophication. Regarding Stockyard Runoff it is wrong to think the algal blooms followed by eutrophication as risk, the actual risk is the increased biological oxygen demand/decreased dissolved oxygen. The risk in soil disturbance
is the erosion, flooding; clogged shipping channels and harbors and thinking about pesticides
, they are in risk for reproductive failure, poisoning, and/or death (pollinators, pets, livestock, predators, children)
.
