Answer:
253.585 square inches
Explanation:
The figure can be decomposed into 2 rectangles and a quarter circle.
Area of the figure = area of rectangle 1 + area of rectangle 2 + area of ¼(circle)
✔️Area of rectangle 1 = Length × width
Length = 10 in
Width = 6 in
Area of rectangle 1 = 10*6 = 60 in²
✔️Area of rectangle 2 = Length × width
Length = 10 in
Width = 6 + 7 = 13 in
Area of rectangle 2 = 10*13 = 130 in²
✔️Area of ¼(circle) = ¼(πr²)
r = 9 in
π = 3.14
Area of ¼(circle) = ¼(3.14*9²) = 63.585 in²
✅Area of the figure = 60 + 130 + 63.585 = 253.585 square inches
which of the following events does not occur in spermatogenesis
Answer:
The mitochondria and Golgi apparatus are packaged into the head of the sperm.
Explanation:
Spermatogenesis is the production of male germ cells. Sufficient stimulation with sex hormones, especially testosterone, and a lower temperature, which is achieved by placing the testicles in the scrotum, are required for the correct course of spermatogenesis. Sperm production has three phases: reproductive, growth and maturation. At the beginning of sperm development are spermatogonia, which are male primordial cells. They have a spherical shape and are located at the edges of the seminal canals. Spermatogonia is mitotically divided. On the one hand, in order to preserve their numbers, and on the other hand, their division produces primary spermatocytes, which lie above the layer of spermatogonia. Primary spermatocytes are diploid, but after the first meiotic division, haploid secondary spermatocytes are formed from them. They still have double chromatids, so a second meiotic division soon occurs, the product of which is spermatids. Spermatids are already fully haploid and do not divide further. Spermatids then undergo a process of spermiogenesis, in which the nucleus condenses, forming a flagellum and losing most of the cytoplasm and some organelles. Immature sperm travel through the seed-forming canals to the epididymis, where they are definitively matured. This whole process takes about 72 days.

Describe how the EMG signal (a voltage) arises from muscle activity
Answer: The EMG signal is a biomedical signal that measures electrical currents generated in muscles during its contraction representing neuromuscular activities. The nervous system always controls the muscle activity (contraction/relaxation). ... EMG signal acquires noise while traveling through different tissues. EMG signals are recorded by placing electrodes close to the muscle groups. When the muscle is activated, the length of the muscle decreases and the muscle, skin and electrodes move with respect to one another. At that time, the electrodes will show some movement artifacts
Explanation:
EMG signals are recorded by positioning electrodes close to the muscle groups. It is the arrangement that helps in the monitoring of EMG signals from muscle activity.
What do you mean by EMG signals?EMG signals may be defined as a biomedical signal that estimates electrical currents provoked in muscles during their contraction illustrating neuromuscular activities.
When the muscle is stimulated for any mechanism, the length of the muscle declines, which leads to the muscle, skin, and electrodes moving with regard to one another.
The EMG signals always arise from the electrical activity of the muscle fibers which are stimulated during the time of contraction.
Therefore, EMG signals are recorded by positioning electrodes close to the muscle groups. It is the arrangement that helps in the monitoring of EMG signals from muscle activity.

Which of the following is NOT a function of the stem in a plant?
o absorb water
store nutrients
produce new plant cells
O support flowers and leaves
Answer: Absorb water
Explanation: i took the quiz the other guy is wrong
Absorbing the water from soil is function of root and not a stem. Thus, option B is correct.
What is stem?The structural part of plant, that supports leaves, flowers, and fruits is called as stem. Stems are frequently differentiated for storage, asexual reproduction, protection, or photosynthesis.
The stem is divided into nodes and internodes. Node consist of buds and leaves, that can grow into the branches. It also gives rise to adventitious roots. The function of internode is to distance one node from another.
Stem supports and uprights leaves, flowers and fruits. The stem keeps the leaves in the light and provides the plant with a place to hold the flowers and fruit. It transports fluid between xylem and phloem roots and shoots. Therefore, transportation of water and nutrients is the function of stem, and not absorption. Hence, option B is correct.

Explanation:
The above graph shows how temperature affects the rate of a reaction that uses the catalase enzyme. What trend is shown by the graph?
A.
Between zero and twenty-seven degrees Celsius, the rate of the reaction increases as the temperature increases.
B.
Between thirty-seven and sixty degrees Celsius, the rate of the reaction increases as the temperature increases.
C.
Between zero and twenty-seven degrees Celsius, the rate of the reaction decreases as the temperature increases.
D.
Between sixty and one hundred degrees Celsius, the rate of the reaction decreases as the temperature increases.
Answer:
the answer is A.
Explanation:
B and C are wrong because they are describing the opposite of what is happening in the graph. D is wrong because there is no change in the reaction rate between 60 degrees and 100 degrees.
The rate of the reaction rises with temperature between zero and twenty-seven degrees Celsius, hence option A is correct.
How does enzyme activity is affected?At various temperatures, catalase functions in different ways. The catalase enzyme becomes more active as the temperature rises from 0°C to about 30°C Up to 100°C, and catalase activity declines as the temperature rises.
The hydrogen bonds between molecules of hydrogen peroxide relax as the temperature rises toward the optimal point, facilitating catalase's reaction with the molecules.
Temperature raising speeds up a process, and lowering temperature slows it down. If the temperature rises over the optimal range, the enzyme denatures and its structure is destroyed.
Therefore, but extremely high temperatures can denature an enzyme, causing it to lose its form and cease functioning. Every enzyme has a preferred pH range, hence option A is correct.

Answer: what does the question say i cant see the attachment?
Explanation:
Answer: 3. anticodon, 4. amino acid, 5. In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis. 6. The process of gene expression involves two main stages: Transcription: the production of messenger RNA (mRNA) by the enzyme RNA polymerase, and the processing of the resulting mRNA molecule. 7. 64. 8. One codon, AUG, specifies the amino acid methionine and also acts as a start codon to signal the start of protein construction. There are three more codons that do not specify amino acids. These stop codons, UAA, UAG, and UGA, tell the cell when a polypeptide is complete. 9. In the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized. When completed, the mRNA detaches from the ribosome, and the protein is released. plzz mark brainliest

Explanation:
The production of red blood cells is regulated by a feedback loop involving erythropoietin. In non-disease states, the production of red blood cells is equal to the destruction of red blood cells, thus maintaining sufficient red blood cells to deliver adequate oxygen to the body's tissues. However, when the number of red blood cells decrease and oxygen levels are low, erythropoietin is produced by the liver and kidneys to increase the production of red blood cells. Is this a positive or negative feedback loop
Answer:
Negative feedback.
Explanation:
The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.
