In cattle, the allele for short horns (S) is dominant over the allele for long horns (s). Two short horn cows are bred and produce four offspring. Three have short horns and one has long horns
What are the most likely genotypes of the parents7
A SS and ss
B Ss and Ss
C SS and Ss
D ss and ss
Answers
the answer to your question is C. SS and Ss
In cattle, the allele for short horns (S) is dominant over the allele for long horns (s) and two short horn cows are bred and produce four offspring, of which three have short horns and one has long horns, so the genotypes of the parents are Ss and Ss which are present in option B.
What is the monohybrid cross?monohybrid cross in which a single trait is involved, such as the cow's horn length, and the short horn length is dominant over the long horn length, so the genotype of the purebred short horn is SS and the genotype of the purebred long horn is ss. The heterozygous parents will produce three short and one long horned offspring, as shown in the following cross.
Hence, when two short horn cows are bred and produce four offspring, of which three have short horns and one has long horns, the genotypes of the parents are Ss and Ss which are present in option B.

which kind of cells carry out the process of cellular respiration?
Answers
All living cells must carry out cellular respiration. It can be aerobic or anaerobic respiration. Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells, while Mitochondria carry out the cellular respiration in eukaryotic cells. They are also called as the 'Power house' of the cell as they produce the energy needed to the cell to function properly.

A)
50 cm of precipitation.
B)
100 cm of precipitation.
200 cm of precipitation.
D)
250 cm of precipitation.
Answers
Answer:
D
Explanation:
Savannah grassland biome is found in an area with an average precipitation of 76.2-101.6 cm. Therefore, option B is correct.
What is the savannah grassland biome?A region of grassland with scattered trees or groups of trees is how the savanna biome is frequently defined.
The savanna is a dry environment, making it difficult for tall plants like trees to flourish. The trees and grasses that thrive on the savanna have adapted to the dry climate and limited water supply.
In regions with savanna growth, a tropical wet and dry climate is prevalent. The annual precipitation averages between 30 and 50 inches, while the mean monthly temperatures are at or above 64 degrees Fahrenheit. Less than 4 inches are received per month during the dry season for at least five months out of the year. Hence, option B is correct.

Answers
Answer:
D. Warmed air sinks is not a normal convection cycle outcome
Explanation:
Warm air is buoyant and rises. Cold air is dense and sinks.
Think of fog in the air. Fog forms in low/cool areas, as the sun comes out and warms up the atmosphere the upper atmosphere, heat flows to cold so upper atmosphere air displaces the fog.
Space heating, the steam or hot water radiators are placed along the floor typically causing convection of warm air to rise up over windows and cold walls, breaking up cold air drafts.

DNA is composed of two complementary strands this is reflected in the fact of that
Answers
Answer: The number of adenines in one strand is equal to the number of thymines in the complemetary strand.
Explanation:
Deoxyribonucleic acid or DNA is a molecule that contains the genetic information in all living organisms. So it contains all the hereditary genetic information that has the instructions to development. This DNA molecule consists of two strands that bond together to form a double helix structure. Each strand of DNA is made up of nucleotides which are basic chemical components made of a phosphate group, a sugar group and one of four types of alternative nitrogenous bases. The four types of nitrogenous bases found in the nucleotides are:
Adenine (A)Thymine (T)Guanine (G) Cytosine (C).The sequence of these bases determines how genes are made, and each gene has different biological instructions to create proteins (that will have different functions in the organism). To form a DNA strand, the nucleotides are linked together in chains, alternating with the phosphate and sugar groups.
The nitrogenous bases are complementary between them. Adenine and thymine are complementary, as are guanine and cytosine. So since adenine is complementary to thymines, and cytosine is complementary to guanine, the number of adenines in one strand is equal to the number of thymines in the complemetary strand. And the number of cytosine is equal to the number of guanine.
DNA is composed of two complementary strands this is reflected in the fact of that - The amount of adenine in one strand is always equal to the amount of thymine in the complementary strand.
A stable double helix of DNAthe two strands of DNA are antiparallel which means if one strand is, the 5' → 3' direction of one strand runs opposite to the other strand.The two DNA chains are held together by complementary base pairing between A and T bases and between G and C bases.The hydrogen bonds are found between the bases of the two strands of nucleotides.Adenine forms hydrogen bonds with thymine whereas guanine forms hydrogen bonds with cytosine.This is called complementary base pairing.
Thus, DNA is composed of two complementary strands this is reflected in the fact of that - The amount of adenine in one strand is always equal to the amount of thymine in the complementary strand.

Hydrogen - 3 is a radioisotope with a half life of 12.32 years. How long would it take a 40 g sample to decay down 2.5 g ?
Answers
Answer:
Whether or not a given isotope is radioactive is a characteristic of that particular isotope. Some isotopes are stable indefinitely, while others are radioactive and decay through a characteristic form of emission. As time passes, less and less of the radioactive isotope will be present, and the level of radioactivity decreases. An interesting and useful aspect of radioactive decay is half-life, which is the amount of time it takes for one-half of a radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by coTnditions and is independent of the initial amount of that isotope.
Consider the following example. Suppose we have 100.0 g of tritium (a radioactive isotope of hydrogen). It has a half-life of 12.3 y. After 12.3 y, half of the sample will have decayed from hydrogen-3 to helium-3 by emitting a beta particle, so that only 50.0 g of the original tritium remains. After another 12.3 y—making a total of 24.6 y—another half of the remaining tritium will have decayed, leaving 25.0 g of tritium. After another 12.3 y—now a total of 36.9 y—another half of the remaining tritium will have decayed, leaving 12.5 g. This sequence of events is illustrated in Figure 15.1 “Radioactive Decay”.

Some organisms, such as bacteria, reproduce asexually; whereas, other organisms reproduce
sexually. Which statement correctly states why one type of reproduction is beneficial over the
other?
A. Asexually reproduced offspring are more genetically diverse.
B. Asexual reproduction produces offspring genetically different from parents.
C. Sexual reproduction can produce a large number of offspring very quickly.
D. Sexual reproduction produces organisms that are genetically diverse.
Answers
Answer:D
Explanation: A isn't right because during asexual reproduction there is no exchange of genetic characteristics thus the offsprings retain the genetic characteristics of their parents and there is no diversity.
Sexual reproduction on the other hand involves the fusion of gametes and the exchange of genetic characteristics thus the offsprings are diverse and are not identical to their parents as is the contrary in asexual reproduction.
Sexual reproduction produces organisms that are genetically diverse.
Sexual reproduction involves the combination of chromosomes from both parents. This combination of chromosomes introduces variation into the population. This combination does not occur in asexual reproduction.
Hence, the statement that correctly states why one type of reproduction is beneficial over the other is that sexual reproduction produces organisms that are genetically diverse.
