Mammals and reptiles have a similar reproductive cycle in one respect. Internal fertilization.
What is the reproductive cycle?Menstrual, regenerative, proliferative, and secretory phases are its four stages. The period between the first day of one menstruation and the first day of the subsequent menstruation is known as a cycle, and it typically lasts between 21 and 40 days. A cycle typically lasts 28 days.
What are the two reproductive cycles and how many types of reproductive cycle are there?A fertile female has two regular cycles: the ovarian cycle, which takes place in the ovary's cortex, and the menstrual cycle, which takes place in the uterus' endometrium. The hormones secreted during the various periods of the ovarian cycle regulate the phases of the menstrual cycle.
Estrual and menstrual cycles are the two different types of reproductive cycles. Estrual and menstrual cycles are the two recognised forms of reproductive cycles, and an ovarian cycle is the time period between two subsequent ovulations.

What does the data reveal about the relationship(s) between the impactor's mass and crater depth?
Answers
Answer:
For each ball, the crater diameter increased as the height of the ball drop increased. My conclusion is that crater diameter increases with increasing mass. Also as the height of the ball increases, so does the crater diameter. Thus crater diameter is proportional to the mass and velocity of the impactor.

Select a potted plant from the garden and keep it in a room for five days as shown in the diagram. After five days, you can see that most of the leaves of the plant change yellow. What could be a systematic method to ask right questions? Make a hypothesis or educated guess, conducting scientific experiment and activities about the existing facts to figure out a conclusion in accordance with the scientific learning process.
Answers
Answer:
Explanation:
To systematically investigate the yellowing of the plant's leaves, you can follow these steps:
1- Observation: Observe and note that after five days in the room, most of the plant's leaves have turned yellow.
2- Question: Ask yourself, "Why did the leaves of the potted plant turn yellow after being kept in the room for five days?"
3- Hypothesis: Make an educated guess about the possible cause of the yellowing. For example, you could hypothesize that the lack of sunlight in the room caused the leaves to turn yellow.
4- Experiment: Design an experiment to test your hypothesis. Place another potted plant in a different room with similar conditions but with sufficient sunlight.
5- Data collection and analysis: Record and compare the condition and color of the leaves in both plants after five days. If the plant with sunlight has green leaves while the one in the room still has yellow leaves, it supports your hypothesis.
6- Conclusion: Based on your observations and the results of the experiment, conclude that the lack of sunlight may be the cause of the yellowing of the plant's leaves.
By following these steps, you can systematically ask the right questions, form a hypothesis, conduct an experiment, and reach a conclusion using the scientific learning process.

Answers
Controlling the practical applications and environmental behaviour of sewage sludge and the biochar that is produced from it depends on the characterization of P speciation.
Sewage sludge is a byproduct of municipal wastewater treatment procedures that cannot be avoided, and turning it into high-value biochar is a good way to make use of this resource. Controlling the practical applications and environmental behavior of sewage sludge and the biochar that is produced from it depends on the characterization of P phosphorus speciation. The mobility and bioavailability of P phosphorus are directly related to its speciation, however there is still a knowledge vacuum in P phosphorus speciation that has to be filled by a thorough investigation using both theoretical prediction and currently available experimental methodologies and techniques.
This study combined conventional P fractionation with consideration of the main concomitant elements (Al, Ca, and Fe), advanced analytical techniques (solution and solid-state 31P NMR, X-ray diffraction (XRD), and theoretical simulation with respect to the solubility of the major elements in various acid-base extractants, in order to achieve a comprehensive understanding of P speciation.

Draw a model showing what would happen if poison blocked our cell ability to make tRNA
Answers
tRNA (transfer RNA) is a type of RNA molecule that plays a crucial role in protein synthesis. It carries amino acids to the ribosome, which is the site of protein synthesis, where the amino acids are joined together to form a protein chain.
If poison were to block our cell's ability to make tRNA, it would disrupt protein synthesis and affect the production of essential proteins in the body. This could lead to a range of symptoms, depending on the proteins that are affected.
For example, if the poison blocked the production of tRNA molecules that carry amino acids required for the formation of enzymes involved in digestion, it could lead to problems with digestion and absorption of nutrients. If the poison blocked the production of tRNA molecules that carry amino acids required for the formation of muscle proteins, it could lead to muscle weakness and atrophy.
In severe cases, such as if the poison blocked the production of tRNA molecules that carry amino acids required for the formation of essential proteins involved in the functioning of vital organs such as the heart or lungs, it could be fatal.

What are constants and variables in an experiment?In an experiment, constants are the factors that are kept the same throughout the experiment. Variables are the factors that are changed or measured during the experiment.
Constants are important because they help to ensure that the results of the experiment are accurate. If one or more constants are changed, it can be difficult to determine which factor is causing the change in the results.
Variables are important because they allow the experimenter to test the relationship between different factors. By changing one variable and keeping the others constant, the experimenter can see how the change in the variable affects the results of the experiment.

3. The reproductive system has both endocrine and exocrine functions. The exocrine function is stimulated by this hormone produced in the anterior pituitary______ and produces this in the male____
4. The endocrine functions is stimulated by this hormone in the anterior pituitary _____ and produces this in the male_____
Answers
1. The exocrine function is stimulated by this hormone produced in the anterior pituitary: follicle-stimulating hormone (FSH), and produces ova (eggs) in the female.
2. The endocrine function is stimulated by this hormone in the anterior pituitary: luteinizing hormone (LH), and produces estrogen and progesterone in the female.
3. The exocrine function is stimulated by this hormone produced in the anterior pituitary: luteinizing hormone (LH), and produces sperm in the male.
4. The endocrine function is stimulated by this hormone in the anterior pituitary: follicle-stimulating hormone (FSH), and produces testosterone in the male.
1. The exocrine function of the reproductive system in females is stimulated by the hormone produced in the anterior pituitary called follicle-stimulating hormone (FSH), which promotes the production of ovarian follicles. The exocrine product in females refers to the release of eggs or oocytes from the ovaries during ovulation.
2. The endocrine function of the reproductive system in females is stimulated by the hormone luteinizing hormone (LH) produced in the anterior pituitary. LH triggers the release of estrogen and progesterone from the ovaries, which regulate the menstrual cycle, promote the development of the uterine lining, and prepare the body for pregnancy.
3. The exocrine function of the reproductive system in males is stimulated by the hormone produced in the anterior pituitary called luteinizing hormone (LH), which stimulates the production of testosterone in the testes. Testosterone is the primary male sex hormone and is responsible for the development of male reproductive organs and secondary sexual characteristics.
4. The endocrine function of the reproductive system in males is stimulated by the hormone follicle-stimulating hormone (FSH) produced in the anterior pituitary. FSH promotes the production of sperm cells (spermatogenesis) in the testes.
Overall, the reproductive system has both endocrine and exocrine functions, with the anterior pituitary gland playing a crucial role in regulating these functions through the production of specific hormones.

Eye color is and example of

c. Transcriptional control
d. Gene regulation
Answers
Answer:
b. Gene expression
Explanation:
The eye color trait is controlled by polygenetic heritability. A group of genes is responsible for the trait manifestation, and they must be associated to transmit the characteristic.
Eye color in a person is produced by pigments in the iris´ cells called melanocytes. At least two or more genes control melanin synthesis in the iris. Melanosomes are cellular structures produced by melanocytes, where melanin is produced and stored. Different genes control the eye color by its expression. We can name two of them as examples. There is a gene called OCA2 that codifies for the P protein synthesis. This protein plays an important role in the amount of melanin produced. The less P protein, the less melanin the cell will produce, which leads to blue eyes. Another gene called HERC2 contains a region known as intron 86 that controls the OCA2 gene, by allowing or inhibiting its expression.

What is the flexibility of spider silk determined by the structure of its molecules
Answers
The flexibility of spider silk determined by the structure of its molecules is quite strong.
The components that make up spider silk are what give it its flexibility. Proteins called fibroins, which are made up of amino acids organised in a certain sequence, make up spider silk. The arrangement of amino acids in fibroin proteins results in a helical structure, which is held together by hydrogen bonds between the amino acids.
The fibroin protein chain's exact arrangement of amino acids and hydrogen bonds produces a special blend of strength and flexibility. The silk is flexible enough to stretch and absorb energy without breaking and robust enough to resist significant stress. Spider silk is a fantastic material for many uses, including clothes, medical equipment, and even bulletproof vests, thanks to its unique mix of qualities.
