Which organism obtains energy without directly depending on another organism

Answers

The organism that obtains energy without directly depending on another organism is a PLANT.

PLANTS are organisms which are capable of manufacturing their own food  through the process of photosynthesis.

Photosynthesis is defined as the process by which plants use low energy containing inorganic compounds (example carbondioxide and water) in the presence of sunlight, as energy, to produce high energy organic compounds such as sugar. These sugar are used as source of energy in the plant cells.

While animals are the organisms that directly depend on plants( another organism)

Therefore, the organism that obtains energy without directly depending on another organism is a PLANT.

Answers

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:

XylemPhloem

The 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.

Which of the following is the reason in how the anterior pituitary differs from the
posterior pituitary?
O A) the hypothalamus controls the release of posterior pituitary hormones but not the anterior
pituitary
B) the anterior pituitary makes its own hormones; the posterior pituitary releases hypothalamic
hormones
C) the posterior pituitary works independently of the hypothalamus
D) the anterior stores hormones produced by the posterior pituitary

Answers

Answer:

B) the anterior pituitary makes its own hormones; the posterior pituitary releases hypothalamic hormones

Explanation:

The pituitary gland is referred to as "master gland" because it coordinates the activities of other endocrine glands. The pituitary gland is composed of two lobes namely: anterior pituitary and posterior pituitary. These two lobes are individually controlled to release several hormones by the HYPOTHALAMUS.

However, one major difference between the anterior and posterior pituitary lobe is that; the posterior pituitary DOES NOT MAKE ITS OWN hormone, hence, releases the hormones (oxytocin and ADH) it stores but produced by the HYPOTHALAMUS. On the other hand, the anterior pituitary PRODUCES ITS OWN hormones but waits for hypothalamic signal to release them.

What is a carnivore?

A carnivore is also referred to as a carnivorous animal and it can be defined as a type of animal whose food and energy requirements are primarily derived from animal products, especially by hunting and scavenging.

This ultimately implies that, a carnivore is an animal that only feeds on other animals such as deers, cows, zebras, rather than grasses or plants.

In conclusion, decomposers are a group of microorganism such as fungi and bacteria, that consumes the rest of the body of a dead or decaying organism after a carnivore has fed on it.

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

Answers

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.

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.

Answers

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.

Describe how the EMG signal (a voltage) arises from muscle activity

Answers

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.
