Answers

Answer 1

Answer:

A

Explanation:

chromosomal mutation definition. A mutation involving a long segment of DNA. These mutations can involve deletions, insertions, or inversions of sections of DNA. In some cases, deleted sections may attach to other chromosomes, disrupting both the chromosomes that loses the DNA and the one that gains it.

7. (True Story) In Denmark, a husband and wife who had been unsuccessfully trying to have a
baby went to a fertility clinic. Sperm and eggs were collected from father and mother, and
combined in a petri dish, creating several "test-tube babies". These babies were implanted in the
mother and 9 months later she ſlelivered twins, one with lightly pigmented skin and one with
darkly pigmented skin. Because this seemed strange, a DNA test was conducted and it was
found that both children were related to the mother, but only the light skinned child was related to
the father. How can this be explained? (Hint, there was no infidelity)

Answers

Answer:a

a possible explanation for this occurrence is that a test tube or dropper was accidentally used repeatedly without being sterilized, causing sample cross-contamination. DNA in this test case did not confirm that the father of the second child was another client of the fertility clinic who had never met the mother...therefore this is a possibility.

Explanation:

The water hyacinth is an invasive species that can spread extremely fast, blanketing a water surface in a very short period of time. It can limit boat traffic, swimming, and fishing, and it can deprive native plants and animals of sunlight and oxygen, thus reducing the local biodiversity. This situation demonstrates _______. a. how migratory patterns change in response to alterations in an ecosystem b. the effects of symbiosis c. the effects of local evolution or migration on an ecosystem d. how changes in biodiversity impact an ecosystem

Answers

1Answer:

The correct answer is - D. how changes in biodiversity impact an ecosystem.

Explanation:

The water hyacinth is an invasive plant species that rapidly grows and creates a thick layer over the water surface in almost every aquatic ecosystem. The growth of the layer of this species causes problems to the environment, ecosystem, humans, and other species.

These aquatic plants reduce the oxygen level and other nutrients from the ecosystem it is introduced and affect the biodiversity by increasing heavy metals and contaminants.

The layer of this plant inhibits photosynthesis that decreases sugar and energy production and blocks the boat and ship movements and economically as well.

Answer:

The correct answer is D

Explanation:

How could a change in the DNA sequence of a single gene affect an organism?
The organism would likely no longer be able to produce offspring.
The gene could code for carbohydrates instead of proteins.
The function of a protein encoded by the gene could change.
DNA could change into RNA.

Answer:

1. Notochord.

2. Dorsal hollow nerve cord.

3. Pharyngeal slits.

4. Pharyngeal slits.

5. Notochord.

6. Dorsal hollow nerve cord.

Explanation:

A living system can be defined as the internal systems found within living organisms and how different materials circulate within these organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, circulatory system, and digestive system.

A chordate can be defined as an animal found in phylum chordata of the animal kingdom such as vertebrates, cephalochordates, tunicates, etc.

The four (4) shared anatomical features or characteristics of chordates includes the following;

1. Notochord: found between the digestive tract and nerve cord.

2. Dorsal hollow nerve cord: in some embryos this develops into the central nervous system.

3. Pharyngeal slits: in invertebrate chordates can be involved in filtering food from water ingest through the mouth.

4. Pharyngeal slits: in jawed fish this provides support for the jaw.

5. Notochord: provides skeletal support.

6. Dorsal hollow nerve cord: is derived from the ectoderm.

Anything that contains atoms emits infrared radiation. Therefore, option (D) is correct.

What is Infrared radiation?

All objects, living or non-living, emit some amount of infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. The amount and wavelength of the infrared radiation emitted by an object depends on its temperature, with hotter objects emitting more and shorter-wavelength infrared radiation.

This is the principle behind the use of infrared cameras and thermal imaging technology to detect and measure heat in a variety of applications, including night vision, medical imaging, and industrial inspections.

Why is the structure of a
nucleosome so important?

Answers

Answer:

In eukaryotes, nucleosomes play major roles in chromatin organization and gene expression  

Explanation:

In eukaryotic organisms, chromosomal DNA is packaged with the help of proteins called 'histones' to form chromatin. The nucleosomes represent the basic packing units of the chromatin. Each nucleosome is composed of a histone octamer containing each two histones H2A, H2B, H3 and H4 wrapped around by 147 bp of DNA. Nucleosomes act as scaffolds to form higher-order chromatin structures (i.e., 30-nm chromatin fibers and condensed chromosomes). Moreover, nucleosome histone proteins can be chemically modified at defined amino acid residues, and thus nucleosomes also provide an epigenetic layer of information that can promote or inhibit gene expression.

10 pounds of seal for a killer whale to gain one pound (10:1). how many pounds of seal will it have to eat to gain 20 pounds of killer whale?

Answers

Answer:

200

Explanation:

20 times 10 is 200 easy

Answer:

200

Explanation:

Multiply 10 by 20 and you'll get 200.

10 pounds = 1 pound gained

? = 20 pound gained

10 : 1

? : 20

1 x 10 = 10

20 x 10 = 200

Hence, the killer whale will have to eat 200 pounds of seal to gain 20 pounds.
