Elina [12.6K]

Answer:

A. The heartbeat can be heard

Explanation:

After the first trimester, during the fourth month, the heartbeat of the fetus becomes loud enough to be heard with the help of a stethoscope placed on the abdomen of the mother.

From fifth to the seventh month of the development, kicks and jabs are felt by the mother as the fetal legs grow and develops. Languo, a wrinkled pink colored skin covers the fetus.

Languo is in turn covered with a white greasy substance called vernix caseosa.

From eighth to ninth months, rotation of the fetus places its head pointing towards the cervix to facilitate childbirth later.

The development of testes takes place in the seventh month while the body hairs become disappeared in the eighth month.

Dendrite is to axon what ________ is to ________. A) receiving; sending B) sending; receiving C) reuptake; action potential D) a

svlad2 [7]

Answer: Option A) receiving; sending

Explanation:

The neuron is made up of many parts, they include:

- dendrites, which are branched and helps in receiving impulses from the adjacent neuron

- axon, a long and extended portion of the neuron that the transmission of impulses along its length away from the cell body.

- synapse etc

Thus, dendrites of neurons is involved in receiving impulses into the neuron, while axons is involved in sending impulses away from the neurons

Cellular respiration map

nexus9112 [7]

Explanation:

Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate (through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Further Explanation:

In all eukaryotic cells, mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced.

Oxidative phosphorylation follows; this is a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm. 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)

The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

When tissues are harmed by bacteria, trauma, heat, or any other cause, an inflammatory reaction occurs.

<h3>What happen when a honey bee stings?</h3>

When a honey bee stings or a disease infects damaged cells, chemicals are released. chemicals are a group of substances that include prostaglandins, histamine, and bradykinin. These substances promote swelling by forcing blood vessels to leak fluid into the tissues.

During the inflammatory reaction, the following processes occurred:

Redness, swelling, and loss of function are all symptoms of heat.

Inflammation is the body's natural defense system. Damaged cells, irritants, and infections are recognized by the immune system, white blood cell kills the antigen and stimulates the other defense cell to act. this process is called a macrophage.
