Answer:

B. 5

Explanation:

5 Although neither enzyme has its maximum catalyzing rate at 5, they are equal in their rate of catalyzing ability at this pH. Pepsin has an optimal pH of 3 while trypsin has an optimal pH of 8.

Scientists discover more than ten thousand new species of living organisms every year. What is shared between all of these organ

lara [203]

Answer:

C. They produce and use adenosine triphosphate (ATP).

Explanation:

ATP is the energy currency for the cells of all living beings. It is produced by aerobic or anaerobic respiration in both prokaryotes and eukaryotes. Complete or incomplete oxidation of nutrients obtains ATP. ATP is used by cells to perform all the vital functions. ATP synthesis occurs when phosphate is added to ADP during substrate-level phosphorylation or oxidative phosphorylation. Hydrolysis of ATP includes the release of terminal phosphate and lots of energy which in turn is used by cells.

A stimulus is applied to the back of your hand, which results in the activation of two sensory neurons. the stimulus is applied

Leno4ka [110]

The recruitment of sensory neurons is known as population coding. Population coding is a method used to represent stimuli by applying the joint activities of a number of neurons. Each sensory neuron has a distribution of responses above some set of inputs, and the responses of many neurons may be added to ascertain some value about the inputs.

Match the following:Part A1. Transverse foramina present.2. No canals or foramen present. It articulates superiorly with the sac

Stels [109]

Answer:

1. Transverse foramina present: Cervical

2. No canals or foramen present. It articulates superiorly with the sacrum: Coccyx

3. Receive the most stress: Lumbar

4. Attach to ribs: Thoracic

5. Articulates with hip bones of the pelvis: Sacrum

Explanation:

The vertebral column is a series of 33 bones called vertebrae that play a key role in organ protection, movement of body, and overall support. The column has been divided into 5 different regions with the number of bones.

1. Cervical Vertebrate: These are the group of seven vertebrae of the neck, start immediately below the skull. Two cervical bones C1 and C2 are unique in function. They are responsible for the movement of the head. They have transverse foramina which gives passage to vertebral artery and vein.

2. Thoracic Vertebrae: They are a group of twelve small bones that form the vertebral spine in the upper trunk. The function of the thoracic vertebrae is to articulate with ribs to produce the bony thorax.

3. Lumbar Vertebrae: This is the largest segment of the vertebral column that consists of 5 bones between the rib cage and pelvis. They carry all of the upper body weight providing flexibility and movement to the trunk region. This is why it can receive the most stress easily.

4. Sacrum Vertebrae: There are 5 sacral vertebral fused bones. It connects to the hip bones and play role in forming a strong pelvis.

5. coccyx Vertebrae: These are a group of 4 fused bone. There is no vertebral canal due to a lack of vertebral arches. They provide an attachment site for muscles ligament and tendons. They also play a role in stabilization and support while sitting.

An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, seedlings

Rus_ich [418]

Answer:

The definition is listed in the clarification segment below, and according to the present circumstances.

Explanation:

It undergoes different morphological as well as biochemical modifications mostly during germination. Product contains nutrients and even some hydrolases such as energy, carbohydrates. Owing to the availability of phytic compounds, the seed coat seems to be very durable in nature. Hydrolytic enzymes launch their function by consuming oxygen throughout order to remove this hard coating. In several other processes, including the electron transport system as well as the Kreb process, oxygen also becomes necessary.

The initial phase of germinating seeds requires anaerobic environments where even the enzymes dehydrogenase can function. The subsequent dehydrogenase enzyme brings the electron throughout the electron transport system from either the base to oxygen.
Unless the oxygen frequency is compared with varieties A and B, it can be seen through the analysis that variety B actually absorbed more oxygen. Oxygen intake rates are also depending upon period.
The impact of temperature mostly on absorption of oxygen seems to be present. Shift the supply at low temperatures have a low intake of oxygen, while varieties grown over extreme temperatures use much more oxygen. The metabolism of such a seedling is influenced by temperature. Metabolically active young plants display a larger intake of oxygen.
