Sponges move huge volumes of water through their bodies every day. Although this serves the function of filter feeding for the organism, how might this also provide an “ecosystem” service (something that affects and/or benefits other organisms in their environment)? "which one below is the right answer and why?" a/ They can filter small poisonous fish out of the water that may harm other organisms. b/ Their body chambers serve as places where smaller organisms can live and be protected from certain predators. c/ They produce large numbers of gametes that will become food for other sponges. d/ They create small currents in their microenvironment that help to circulate and clean water locally for other organisms.

Answer 1

Answer: d/ They create small currents in their microenvironment that help to circulate and clean water locally for other organisms.

Contractile vacuoles are organelles that are responsible for excretion function. They perform osmoregulation which manages wastes, water and other needed materials in the cell. They are found in some prokaryoric organisms like the algae, protists, amoeba and other unicellular organisms.

The head of a phospholipid can be descibed as

Answers

Phospholipids are a class of lipids and are a major component of all cell membranes as they can form lipid bilayers. Most phospholipids contain a diglyceride, a phosphate group, and a simple organic molecule such as choline.

Amphipathic character
The 'head' of a phospholipid is hydrophilic (attracted to water - polar), while the hydrophobic (non-polar) 'tails' repel water. The hydrophillic head contains the negatively charged phosphate group, and may contain other polar groups. The hydrophobic tail usually consists of long fatty acid non-polar hydrocarbon chains.

According to the theory of evolution, what characteristics do all living organisms share suggesting that all life-forms on earth arose from a single ancestor?a. they share a common organic chemistry.
b. they exhibit the same basic cell wall.
c. they perform the same mode of reproduction.
d. they have dna within their nucleus.

Answers

Answer;

D. they have DNA within their nucleus.

Explanation;

-According to evolutionary theory, diverse groups of animals evolve from one or a few common ancestors and the mechanism by which this evolution takes place is natural selection.

-Natural selection is the process by which traits that enhance survival and reproduction become more common in successive generations of a population.

-All forms of life are built of cells. A cell is the basic unit of the structure and function of living things. Living things may appear very different from one another on the outside, but their cells are very similar.

When glucose is needed by the cell, which organelles secrete enzymes in order to begin glucose breakdown?

Answers

The firstpath is from the nucleus. DNA from the nucleus, assigns specific job for theorganelles to follow through mRNA. The mRNA goes out from the nucleus andenters the cytoplasm where ribosomes will attach to the mRNA. The ribosome-mRNAcombination binds to the endoplasmic reticulum and signals the tRNA totranslate the message from DNA. A vesicle that contains the enzyme grows outfrom the endoplasmc reticulum ans transport the enzyme to the Golgi body forfurther processing. The main organelle would be the Golgi Body.
