Question 3(multiple choice worth 4 points) (02.04 lc) which best describes the function of chloroplast? allows certa molecules to enter and exit the cell makes food during photosynthesis detoxifies waste products o packages proteins into vesicles

Option B.

Explanation:

Chloroplast is defined as an organelle found in green plants that contains green pigment called chlorophyll responsible for the process of photosynthesis.

Chloroplasts plays an important role in photosynthesis which is to trap light energy from sunlight and convert it into carbohydrate which further used by cells in teh form of adenosine triphosphate  (ATP) and  nicotinamide adenine dinucleotide phosphate hydrogen (NADPH).

Hence, the correct option is B.

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
