The Minimal Chromosome To enable it to be transmitted intact from one cell generation to the next, the linear DNA molecule of a eukaryotic chromosome must have appropriate nucleotide sequences making up three special kinds of regions: origins of replication (at least one), a centromere, and two telomeres. What would happen if such a chromosomal DNA molecule somehow lost: a) all of its origins of replication

Answers

Answer 1

Answer:

The chromosome wouldn’t be able to replicate

Explanation:

Without an origin of replication, the chromosome could not be copied prior to mitosis.

Answers

Answer:

The correct answer is - C.

Explanation:

The central dogma the two-process system that is an essential truth of biology as it is the basis of complete living organisms. It is a particular pattern of information that takes place in our cells by the process known as transcription and translation.

What is the direction of energy flow in an energy pyramid? How much energy is transfered from one step to another?

Answers

Answer:

- The flow of energy is from the lowest level (i.e., the base of the pyramid)  to highest levels

- Approximately 10 percent

Explanation:

The energy pyramid is a diagram that shows the flow of energy between trophic levels in an ecosystem. Each trophic level is characterized by organisms that play specific roles in an ecosystem, for example, photosynthetic organisms (producers) at the base of the pyramid which represent the source of energy for herbivores localized at a higher level. The amount of energy decreases as it moves to higher trophic levels, approximately 10 percent of the energy is transferred from a trophic level to the next level and the remaining energy is lost as heat.

Help me answer this biology question Urgent

Answers

Answer:

1) Producers

2) Photosynthesis

3) Consumers

4) Herbivores

5) Carnivores

6) Decomposers

Explanation:

Juan and Carol were studying invertebrates in biology. They knew that segmented or earth worms preferred a dark, moist habitat. During this lab, they would be investigating the responses of organisms called planaria or Dugesia tigrina. These were simple flatworms that still had a one-way digestive system and a very simple nervous system. Juan and Carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. They shined a light on the dish. Next, they removed the paper and placed a small amount of chicken liver at one end of the dish. They added a few large salt crystals to the water. Finally, they added drops of hot water to the cool water in the petri dish. Their results can be seen in the data table. According to their experiment, all BUT one conclusion is valid. A) Planaria are a fresh-water organism only. B) Planaria are consumers and may be carnivores. C) Planaria have specialized cells to detect light intensity. D) Planaria have specialized cells that detect temperature change. answer and you get all my points plzzz

Answers

Answer:

A) Planaria are a fresh-water organism only.

Explanation:

Planaria are a fresh-water organism only. Although the planaria moved away from the salt crystals, it may be because of the concentration of salt rather than its presence. There are both fresh water and salt water species of planaria. The other three conclusions are supported by the data.

Planaria are consumers and may be carnivores is the correct. Thus option B is correct

What is a planaria?

Planaria  also called cross-eyed worms.

They are the tiny group of  flatworms belongs to phylum Platyhelminthes.

They are free-living organisms in fresh water bodies.

The body are small, measuring around 3 to 15 mm , have a soft, leaf-shaped body covered cilia and spade-shaped head with two eyes

It is otherwise called as flatworms under the ancient class of Turbellaria which is in the branch of Platyhelminthes.

Planaria can sense and respond different stimuli like light where e eyespots can detect light and allow the organism  to react to it.

It can sense Chemical by the help of  their head regions allow them  to smell.

The auricles of the head region can sense touch and allow  them to respond.

Thus option B is correct

Optimum Temperature is 35°C

Optimum PH is 7.0.

Explanation:

The optimum temp of enzymes is 20-35°c. They become inactivated at very low temperature and denatured (destroyed) at very high temp i.e. greater than 45°C. Low molecular weight enzymes are comparatively more heat stable.

The optimum pH of most enzymes is pH 7.0 (neutral pH).

ANSWER

Fossil fuels are formed when biomass is covered by sediment, and the biomass experiences high temperature and pressure over time. The correct option is B.

What are fossil fuels?

Coal, oil, and natural gas are fossil fuels formed from the remains of dead plants and animals that were buried in sedimentary rock layers millions of years ago.

Over time, these organic materials are subjected to high temperatures and pressure, resulting in the transformation of organic matter into fossil fuels.

These hydrocarbons migrate through the surrounding rock over millions of years and accumulate in underground reservoirs, where they can be extracted and used as energy sources.

Fossil fuel formation is a slow process that requires specific geological conditions such as the presence of sedimentary rocks, high temperature, and pressure.

Thus, the correct option is B.

why doesn't the periosteum cover the articular cartilage of a long bone

Answers

The periosteum doesn't cover the portion of bones that contains articular cartilage, which is the cartilage found in joints that keeps the bones from rubbing together. It is not as tightly packed and contains cells that help in bone growth and repair.

The periosteum does not cover the articular cartilage of a long bone because it is not located in the part of the bone where the joint is formed.

The main function of articular cartilage is to facilitate the movement of a joint in any mechanical circumstance.

The periosteum is a membrane that is part of the constitution of the bones, and that is located throughout the entire bone body, with the exception of the area that is destined for the articular surface.

It is found throughout the central part of the bone, that is, it passes through the entire diaphysis and reaches the metaphysis.

It disappears in the epiphysis because it is the area that generates contact with the tissues that make up the joints, necessary for movement.

Therefore, we can conclude that the periosteum is a membrane that covers all the bones, except the area that is destined for the articular surface.

The function of some cyclin-dependent protein kinases (CDKs) has been remarkably conserved in evolution. Indeed, coding sequence for the human protein Cdc2 is able to substitute for the CDC28 gene in S. cerevisae and allow the yeast cell to grow and mate essentially normally. The following sequence near the NH2-end of the molecule is identical in both proteins: Gly-Glu-Gly-Thr-Tyr-Gly-Val-Val-Tyr-Lys-Ala. Does this mean that nucleotide sequences of the two genes coding for this region of the polypeptide are also identical

Answers

Answer:

No, because the genetic code is redundant  

Explanation:

During the translation, a single amino acid may be coded for by more than one codon. It is for that reason that the genetic code is considered to be redundant. Tryptophan is the unique amino acid specified by a single codon. In this case, it is likely that silent mutations at the nucleotide sequence that encode for the Glu-Gly-Thr-Tyr-Gly-Val-Val-Tyr-Lys-Ala protein motif might have accumulated during the evolution of both CDK genes, modifying thus their nucleotide sequences while preserving the same protein sequence.
