This is followed a few months later by a rash and flu-like symptoms. If syphilis is not treated, it may damage the heart, brain, and other organs. It can even cause death. Q: What serious sti can damage the heart, brain and other organs or even cause death, if untreated? Choices: - herpes - chlamydia - cirrhosis - syphilis A:

Ques: Answer the following question given this paragraph: Heterotrophs cannot make their own food, so they must eat or absorb it. For this reason, heterotrophs are also known as consumers . Consumers include all animals and fungi and many protists and bacteria. They consume either autotrophs or other heterotrophs. Heterotrophs show great diversity and may appear far more fascinating than producers. But heterotrophs are limited by their utter dependence on those autotrophs which originally made the food. If plants, algae, and autotrophic bacteria vanished from Earth, animals, fungi, and other heterotrophs would soon disappear as well. All life requires a constant input of energy. Only autotrophs can transform that ultimate, solar source into the chemical energy in food which powers life, as shown in Figure below . Q: Because heterotrophs cannot make their own food, what are they called? Choices: - products - destroyers - customers - consumers A:
Ans: consumers
(Q).
Answer the following question given this paragraph: Lymphatic vessels make up a body-wide circulatory system. The fluid they circulate is lymph. Lymph is a fluid that leaks out of capillaries into spaces between cells. As the lymph accumulates between cells, it diffuses into tiny lymphatic vessels. The lymph then moves through the lymphatic system from smaller to larger vessels. It finally drains back into the bloodstream in the chest. As lymph passes through the lymphatic vessels, pathogens are filtered out at small structures called lymph nodes (see Figure above ). The filtered pathogens are destroyed by lymphocytes. Q: What destroys the filtered pathogens? Choices: - parasites - neutrophils - antibodies - lymphocytes A:
(A).
lymphocytes
Ques:Answer the following question given this paragraph: Like strong acids, strong bases can be harmful to organisms and damaging to materials. Bases have a bitter taste and feel slimy to the touch.

Ans:blue
Answer the following question given this paragraph: A population is a group of organisms of the same species that live in the same area. All the genes in all the members of a population make up the population's gene pool . For each gene, the gene pool includes all the different alleles in the population. The gene pool can be described by its allele frequencies for specific genes. The frequency of an allele is the number of copies of that allele divided by the total number of alleles for the gene in the gene pool. Q: All the genes in all the members of a population make up its what? Choices: - phenotype - diversity - longevity - gene pool A:
gene pool
