Why is the number of hours of daylight 24 seen by the observer at location c on june 21.
Answers
The number of hours of daylight seen by an observer at location c on June 21 is 24. This is due to the fact that June 21 marks the summer solstice in the northern hemisphere, which is the longest day of the year.
During the summer solstice, the sun is at its highest point in the sky, and the tilt of the Earth's axis is such that the observer at location c is receiving direct sunlight for the entire 24 hours of the day.
The summer solstice also marks the beginning of summer in the northern hemisphere, and the sun's rays are the strongest and most direct they will be all year. This causes the days to be longer and the nights to be shorter, with 24 hours of daylight for the observer at location c on the summer solstice.

What is the main source of energy in a shady stream?
O A. Phytoplankton
O B. Algal blooms
O C. Dead leaves
O D. Photosynthetic bacteria
Answers
The main source of energy in a shady stream is called as dead leaves. The correct option is C.
What is the main source of energy?The main source of energy in a shady stream would be dead leaves, which provide organic matter for decomposition and support a food web of decomposers and detritivores.
Photosynthetic bacteria may also contribute to energy production in the stream. Phytoplankton and algal blooms are more commonly found in open, sunlit bodies of water.
In such environments, sunlight is limited, making it difficult for photosynthetic organisms like phytoplankton or algal blooms to thrive.
Dead leaves that fall into the stream become the primary source of energy, as they are broken down by decomposers, providing nutrients for other organisms in the stream ecosystem.
Therefore, the correct option is C.

Answer:
The mRNA will attach to the small ribosomal unit and then the large ribosomal unit. Then the mRNA will be decoded with its codon's tRNA. The anticodon will bring amino acids from the cytoplasm to the mRNA. The tRNA will come in at the A site and a peptide bond will form between amino acids at the A and P sites. Then the empty tRNA will exit the ribosome and this will continue until the stop sequence is reached.

Answers
Answer:
Cell membrane encloses all the cell organelles. In prokaryotes, membrane is absent and so membrane-bound cell organelles are also absent.

Describe each stage of early animal development. Make sure to include the following vocabulary: zygote, mitosis, blastula, ectoderm, mesoderm, endoderm, coelom
Answers
The description of the stage of early animal development is given below:
The StagesZygote: The first stage of animal development starts with the fusion of a sperm and an egg, forming a single cell called the zygote.
Mitosis: The zygote divides into multiple cells through a process called mitosis, resulting in an increasing number of cells in the embryo.
Blastula: As the number of cells increases, they form a ball-shaped structure called the blastula.
Germ Layers Formation: The cells of the blastula differentiate and form three primary germ layers: ectoderm, mesoderm, and endoderm.
Ectoderm: The ectoderm gives rise to the outermost layer of the developing embryo and will eventually form the skin, hair, and nervous system.
Mesoderm: The mesoderm gives rise to the middle layer of the developing embryo and will eventually form the muscles, skeleton, and circulatory system.
Endoderm: The endoderm gives rise to the innermost layer of the developing embryo and will eventually form the digestive and respiratory systems.
Coelom: In some animal species, a fluid-filled cavity called the coelom forms from the mesoderm, providing support for the internal organs and allowing for movement.

TRUE/FALSE. in a fruit fly embryo, a homeotic gene antp determines where legs grow. when the promoter of antp is mutated, a fly ends up with legs growing out of its head in place of antennae. in this mutation
Answers
TRUE, In a fruit fly embryo, the homeotic gene Antennapedia (antp) plays a crucial role in determining the development and placement of body segments, including the formation of legs and antennae. When the promoter region of the antp gene is mutated, it can lead to a transformation of body parts, resulting in legs growing out of the fly's head instead of antennae.
This phenomenon is known as a homeotic mutation or homeotic transformation, where the identity of one body segment is replaced by the identity of another segment due to a genetic alteration. In the specific case described, the mutation in the promoter of the antp gene leads to a misexpression or abnormal activation of the gene in the head region, causing the formation of legs in that area.

O a. 1:4 chance O b. less than 1:4 chance c. 3:4 chance O d. 2:4 chance e. 4:4 chance You cross a red flower with a white flower, and all the seeds result in pink flowers. This is an example of O a. polygenic inheritance. O b. incomplete dominance. O c. multiple allele inheritance. O d. codominance. O e. multifactorial inheritance. The letters for blood types represent O a. different shapes of red blood cells. O b. markers on the surface of blood cells. O c. different types of white blood cells. O d. different shapes of white blood cells. O e.types of hemoglobin in blood cells.
Answers
1) The Punnett square would show that if both parents are carriers (heterozygous), there is a 25% chance (1:4) that their child will inherit two copies of the recessive allele and have cystic fibrosis.
2) In this case, the red and white alleles blend to produce a pink phenotype. Therefore, the answer is (b) incomplete dominance.
1) Cystic fibrosis, the chances of two normal individuals having a child with cystic fibrosis can be determined using a Punnett square. Since cystic fibrosis is an autosomal recessive disease, both parents must carry a recessive allele for the disease in order for their child to inherit it.
The Punnett square would show that if both parents are carriers (heterozygous), there is a 25% chance (1:4) that their child will inherit two copies of the recessive allele and have cystic fibrosis. Therefore, the answer is (a) 1:4 chance.
2) The occurrence of pink flowers resulting from crossing a red flower with a white flower indicates incomplete dominance. In incomplete dominance, the heterozygous genotype results in an intermediate phenotype. In this case, the red and white alleles blend to produce a pink phenotype. Therefore, the answer is (b) incomplete dominance.
Regarding blood types, the letters represent different markers on the surface of blood cells. The blood type system is based on specific antigens (proteins or sugars) present on the surface of red blood cells. These antigens determine the blood type classification (A, B, AB, or O). Therefore, the answer is (b) markers on the surface of blood cells.

Ivan read a story about a population of mice that become stranded in a dark jungle. Some mice were dark brown, while others were white. According to the process of NATURAL SELECTION, predict which color of mice would be more successful living in a DARK jungle
Answers
According to the process of natural selection, in a dark jungle environment, it is more likely that mice with a dark brown coloration would be more successful.
In a dark jungle, where light levels are low, mice with dark brown coloration would have a better chance of blending into their surroundings and remaining camouflaged. This would provide them with a survival advantage by making it more difficult for predators to detect and capture them.
On the other hand, white-colored mice would be more easily visible in a dark jungle, making them more vulnerable to predation. They would stand out against the dark background, making it easier for predators to spot and capture them. As a result, white-colored mice may have a lower chance of survival in such an environment.
Through the process of natural selection, over time, the mice with dark brown coloration would have a higher likelihood of passing on their genes to the next generation. This is because they would have a greater chance of surviving and reproducing successfully, thus increasing the frequency of the dark brown color trait in the population.
