A person has a sex-linked inheritable disease. Which statement is true about the set of chromosomes which are likely to carry the genes for this disease?
1-The gene is present on a single pair of chromosomes.
2-The gene is present multiple pairs of chromosomes.
3-The gene is always present on an X chromosome.
4-The gene is always present on a Y chromosome.
The statement is true about the set of chromosomes that are likely to carry the genes for this disease is the gene is present multiple pairs of chromosomes.
What is an example of autosomal?An autosomal recessive disorder needs two copies of the altered gene to compel the disease.

In order for translation to occur: Please choose the correct answer from the following choices, and then select the submit answer button. transcription must be occurring simultaneously. there must be large numbers of free amino acids present in the cytoplasm. the DNA must produce large numbers of free amino acids. replication must be occurring simultaneously. the nuclear membrane must first dissolve
Answer:
there must be large numbers of free amino acids present in the cytoplasm
Explanation:
In order for translation to occur, there must be a large number of free amino acids in the cytoplasm.
These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.
During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.
Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.
Which explanation provides support for continental drift theory? O Dinosaurs lived on many continents. Coal fields match up across continents. Tropical plant fossils were found in warm areas. Similar rock types are found across continents.
Answer:
Similar rock types are found across continents
Explanation:
Can I have brainliest?
Similar composition of rocks are present across continents that support the theory of continental drift.
Similar rock types are found across continents is the evidence that support the continental drift theory because at the boundaries of two continent there must be similar type of rock present. Scientist Alfred Wegener presented Continental drift theory in the early 20th century.
Wegener noticed similarities between two continents when he pieced together maps of Africa and South America. He noticed that mountain ranges present on both continents line up to each other which means they are made of similar type of rock so we can conclude that similar types of rock are present across continents.

Finally, word came around that the British had raised the white flag of surrender. The use of first-person point of view helps engage readers by allowing them to experience how the narrator feels about the battle. the narrator’s pa feels about the battle. the narrator’s friend feels about the battle. the narrator’s mama feels about the battle.
Answer:

A storm brings two formerly separated populations of beetles together. They look very similar. Under the biological species concept, which of the following would show that the two populations are different species?
A. One population breeds in spring, the other in fall.
B. Males of the two populations have different flight patterns in courtship.
C. When individuals from the two populations mate with each other in the laboratory, the eggs fail to hatch.
D. All of the above is correct.
E. None of the above is correct.
Answer:
The correct option is D: All of the above is correct.
Explanation:
The biological species concept says that species are population groups that, in a real or potential way, can reproduce among each other and that are reproductively isolated from other groups.
Individuals belonging to a species cannot mate with members of other species, and if they do there is not any reproductive success.
The mechanisms of reproductive isolation might be divided in prezygotic and postzygotic.
Prezygotic or Premating mechanisms:
Ecological or due to habitat isolationSeasonal or temporal. This is the case described in option A "One population breeds in spring, the other in fall". These species are reproductively isolated because they differ in their breeding season.Sexual or ethological. This is the case described in option B "Males of the two populations have different flight patterns in courtship". Males belonging to each species behave differently during courtship. MechanicalGametes incompatibilityZygotic or Postmating Mechanisms:
Hybrid inviability. This is the case described in option C which states that "When individuals from the two populations mate with each other in the laboratory, the eggs fail to hatch". Eggs fail to hatch because the zygote is inviable. Hybrid sterilityHybrid decreased fertility. There are different methods of sowing the seeds. Which one of the methods given below is not the methods of sowing seeds used by the farmer?
Answer:
A) Broadcasting B) Seed-drill
Explanation:
Options of sowing seeds are given below.
A) Broadcasting B) Seed-drill C) Transplanting D) Scattering E) None of these
Farmers used two methods for sowing of seeds such as broadcasting and seed drilling. Broadcasting is a method of seed sowing in which seeds are scattered in the field by hands or machines while seed drill is another method of sowing in which a device or machine is used which bury the seed at certain depth and at proper position in the field. In seed drilling method, seeds are sowing in lines while in broadcast, seeds are sown in every part of the field.
