Answer:
A sporangium (pl., sporangia) (modern Latin, from Greek σπόρος (sporos) 'spore' + ἀγγεῖον (angeion) 'vessel') is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. All plants, fungi, and many other lineages form sporangia at some point in their life cycle.
Explanation:
which of the following is an example of a complementary base pair in DNA?
a. A-G
b. T-C
c. A-U
d. C-G
Answer: d. C-G
Explanation:
DNA or deoxyribonucleic acid is a structure which is common in every living organism. The two strands of the DNA are held together by base complementarity between the nitrogenous bases these bases are held by hydrogen bonding. Adenine always pairs with thymine by a triple hydrogen bonding and cytosine is always forms a pair with that of guanine by a double hydrogen bonding. So, in this given situation cytosine or C will show complementarity with that of guanine or G in a DNA structure helping in linking the two strands of DNA to form a single integrated double helical structure.

Given the loss of farming jobs projected in the near future, distinguish at least two factors in a decision one might make to enter the field.
i cant process this lol no matter how much tiems read it
Answer:
this is the suggested answer
Explanation:
A correct answer will discuss two factors from among the following: one factor is despite the projected loss in farming jobs, these jobs are still essential and may still provide for a lucrative and successful career given that the median income level that is significantly higher than the national average. Another factor is the wide variety of careers in this general field, so the information on declining career outlook could be misleading, depending what specific career one is looking into.

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

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:
xylem & phloem are present in both woody and herbaceous stems
Explanation:
Vascular system is present in both, woody and herbaceous stems. Thus, option A, and D are correct.
What are vascular tissues?In vascular plants, A tissue which is complex in nature, formed by more than one type of cells are called as vascular tissues. Two main types of vascular tissues are:
XylemPhloemThe transportation of water from roots to stem and leaves of the plant is carried out by xylem. Xylem consist of tracheids and vessel elements, which have different characteristics, but both play significant role in transportation of water and nutrients.
The soluble organic compounds synthesized during photosynthesis in the plants are transported by another vascular tissue called as phloem, in process called translocation. It consists of sieve elements, parenchymal cells, fibers, and sclereids.
Therefore xylem and phloem are present in both, woody and herbaceous stems.

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.
