Answer:
Chloroplast
Explanation:
This organelle in cells indicates that an organism can harness energy from the sun and other abiotic factors like carbon dioxide to make their own ‘food’. Chroloplasts have chlorophyl piments that contains photosystems centers that harness energy from the sun for photosynthesis. This light energy from the sun is captured and transferred in chemical bonds of manufactured carbohydrates which are stored in the plants. These plants transfer this energy in an ecosystem when they are consumed by higher organisms in the food chain.

Answer: A. scalp hairs grow constantly throughout life.
Explanation:
Hair is a squamous keratinized epithelium which is consist of multi-layered flat cells. Hair are made up of protein called "keratin".
The statement "scalp hairs grow constantly throughout life" is false because at a particular age or due to several factors scalp hairs stop growing.
Scalp hair growth rate depends on three main factors including sex (female hair grows faster than male), age (hair growth slows with age), and ethnicity (Asian hair grows slower than Caucasian hair).
Scalp hair growth stops because of follicle devitalization when the hair length become two or three feet.
Hence, the correct answer is A. "scalp hairs grow constantly throughout life".
Answer:
d. multiple alleles and codominance
Explanation:
ABO blood group is controlled by three alleles instead of the usual two. Hence, it is an example of multiple alleles. These three alleles are IA, IB and i. IAIA genotype leads to production of A antigen hence A blood group. IBIB genotype leads to production of B antigen hence B blood group. When they are present together (IAIB) both A and B antigens are produced resulting in AB blood group. Hence ABO blood group is also an example of codominance.
Both IA and IB are dominant over the i allele. So IAi and IBi will produce A and B blood group respectively. ii genotype leads to O genotype.
Answer:
genetically modified organisms are better and worst
Explanation:
more things are possible with genetically modified organisms but also it can be bad for you
hope this helped
