In your body, different types of cells use different genes. True or false?

Answers

Answer 1

Answer: No. False

Genes are the source of information where the individual is shaped and formed. These are not dependent on the cell type rather, cell types are formed by certain activation in these genes. They are the artist that trigger the formation and function of these cells.

A thermometer is placed in water in order to measure the water’s temperature. What would cause the liquid in the thermometer to drop

Answers

The reason why the liquid in the thermometer drops is because the water's temperature is low. When the temperature of the water is high or hot, the liquid molecules moves faster making them spread farther apart. But when the temperature of the water is low, the kinetic energy of the water molecules decreases allowing them to get closer to each other.

Protists are a group of organisms that are characterized as eukaryotes (they have cells with nuclei) that are neither plants nor animals nor fungi. They are very diverse, and there are many hypotheses about their classification. The cladogram for protists is constantly changing and, sometimes, there are opposite hypotheses that both have data to support them. What is the implication of a changing hypothesis? It is acceptable because data are still being collected. It is acceptable because everything in science should always change. It is not acceptable because the correct answer needs to be found. It is not acceptable because science never changes.

Answers

It is acceptable because data are still being collected.

Protists obtain food in 3 ways. They produce their own organic molecules, ingest, and absorb. Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a food vacuole around the food item. Inside the food vacuole, enzymes digest the food. Absorptive protists on the other hand, absorb food molecules across their cell membrane which takes place through diffusion. Absorptive protists play a key role in decomposition. They are considered as important decomposers. Major producers like photosynthetic protists use light energy to manufacture their own food.

The hypothesis is constantly changed because data are still being collected, and due to this, hypotheses are accepted.

Further Explanation:

Protists are considered as first eukaryotes to be identified. They are different from prokaryotes because they have a well-defined cytoskeleton. They consist of different organelles and nuclear envelope. Protists have a varied range of cell surfaces. They can easily stand in an unfavorable environment due to the presence of outer covering. They have flagella for the locomotion. They can either be autotroph and heterotrophs. This is because they ingest food particles by pulling them in the intracellular vesicles referred to as phagosomes or vacuoles. They can produce by means of asexual and also by the sexual method. Protista that produces sexually undergoes meiosis, which is a reductional division resulting in the formation of haploid cells.The progeny that are produced by the union of two haploid cells allowed the formation of new allelic combinations by genetic recombination.

Cladistics is a process of classifying organisms depends upon their shared traits. The cladogram for Protista is continuously altered, and, at times, there are contradictory theories that together have data to support the hypothesis. It is suitable because facts are still being collected.

For questions 1-5 decide whether the example is a producer, consumer or decomposer. A rabbit is an example of a _________. Question 1 options: A.Producer B.Consumer C.Decomposer

Answers

a rabbit is a consumer

a consumer eats plants or other animals. Such as: lion, bear, horse, human, etc. Organisms that eat autotrophs; these organisms are called herbivores or primary consumers -- an example is a rabbit that eats grass. The next link in the chain eats herbivores - these are called secondary consumers -- an example is a snake that eats rabbits.

What could happen to the reproductive process of mosses during a drought? The flagellated sperm would not be able to swim to the eggs for fertilization. The flagellated sperm and eggs would go dormant until water was available. Mitosis in the sporophyte would cease and the reproductive cycle would stop. Meiosis in the sporophyte would cease and the reproductive cycle would stop.

Answers

The answer is The flagellated sperm would not be able to swim to the eggs for fertilization.

Their life cycle of mosses has alternation of generation - a haploid gametophyte and a diploid sporophyte. Gametophyte produces haploid gametes which fuse to form a diploid zygote. The zygote grows into diploid sporophyte which produces haploid spores. The spores grow into gametophyte and the cycle begins again.
Mosses require water for reproduction. Before fertilization, the sperm swims to an egg through the water. Therefore, mosses require water for successful fertilization. In drought periods, without water, the sperm cell could not swim to the egg cell.

Answer:

The flagellated sperm would not be able to swim to the eggs for fertilization.
