14. Which of the following statements is/are correct? A. Most, if not all, members of Porifera are substrate feeders.
B. Members of Porifera lack endoderm and ectoderm
C. Sponges are a member of the phylum Cnidaria
D. Sponges do not reproduce by sexual reproduction and instead only reproduce asexually.
E. Given the following on the organism
I. An animal
II. Multicellular
III. Lacks tissues
IV. Lacks organs
V. Asymmetrical
This organism must be a member of the Phylum Porifera

Answers

Answer: Option E

Explanation:

Most of all poriferans/ sponges are suspension or filter feeders. Suspension feeders are organisms that each food materials which are suspended in their environment ie sea water, while filter feeders filter their food source from water by drawing water containing bacteria and organic matter in through their ostia(pores). Substrate feeders at organism that live in or on their food source.

Members of the poriferans do hava an ectoderm (epidermis) and an endoderm including a non-cellular late that is present in between the two layers.

No, they do not belong to the phylum cnidaria but porifera. Cnidarians including hydra, sex anemones, jellyfish etc and these have features that different from that of the sponges e.g the presence of nematocysts in cnidarians

Sponges can reproduce both sexually and asexually. Sexually by releasing larva fertilized in the sponge into water where they float around for some days and then proceed to adhere to a solid surface and begin their growth into adults. Asexually by budding

They are multicellular, lack tissues, are animals, lack organs and are asymmetrical. These are th distinguish features of poriferans

Answer: Option E.

Explanation:

Phylum porifera are group of organisms that live in aquatic habitats both marine and freshwater. They are diploblastic I.e they have two germ layers. They are assymetrical . They have round or vase-like or sac- like shape. They are multicellular and have bodies full of pores. They lack tissues and organs. Sponges are members of the phylum porifera.

Which of the following features is not universally accepted as a sign of physical attractiveness? A. facial symmetry B. a curvy figure C. average body type D. average features Please select the best answer from the choices provided A B C D

Answers

A curvy figure is not a universally accepted sign of physical attractiveness. Therefore option “B” is correct.

What is physical attractiveness?

It is the measure of the degree to which a person can look and aesthetic pleasing.  Facial symmetry and sociocultural and personal choices of a person are evaluating factors.

Facial symmetry is based on the symmetry of the face of a person and youthfulness. It helps in determining the beauty of a person.

Sociocultural depend on how a person combines both social and cultural factors. Factors affecting are such as personal beliefs,  and values. Personal choices vary from person to person as everyone has different choices.

Physical attractiveness is the evaluation of the physical appearance of a person.

What is the effect of an enzyme on the energy of a chemical reaction

Answers

Answer:

it increases speed of chemical reaction

Final answer:

Enzymes are proteins that speed up chemical reactions by lowering the activation energy, or the energy required for a reaction to take place. This makes reactions happen more efficiently and quickly.

Explanation:

An enzyme is a type of protein that accelerates, or catalyzes, chemical reactions. In relation to their effect on the energy of a chemical reaction, enzymes lower the activation energy. The activation energy is the energy threshold that must be met in order for a chemical reaction to occur. By decreasing this energy barrier, enzymes facilitate the process and make it proceed faster than it would without the enzyme.

For example, let's take the digestion of food in your body. The enzymes present in your digestive system speed up the chemical reactions that break down large food molecules into smaller units. This is because these enzymes reduce the activation energy required for these reactions, enabling the reactions to happen more efficiently and quickly.

The reason that there are Okazaki fragments during DNA replication is ultimately because:A) Some parts of the chromosome are made of RNA and different polymerases have to be used
B) Polymerases can only synthesize in the 5' to 3' direction
C) There are only enough dNTP's to support quick replication on one strand, so the other strand lags behind it
D) It is necessary to "slow down" one of the strands so that replication does not occur before cells have a chance to grow

Answers

Answer:

B) Polymerases can only synthesize in the 5' to 3' direction

Explanation:

The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.

Answers

Answer:

Water initially moves into the root hair cells by osmosis, because the mineral content of the cells is higher than that of the surrounding environment. Thus, a root pressure is established and extends into the microscopic tubes of the xylem.
