Can anyone help me in biology it’s hard and I don’t understand it

Answer:

The organism cant breathe.

Explanation:

With no diaphragm you will die. If there is no diaphragm in the body, the breathing will stop, which leads to death.

The nitrogen cycle which is converted to an intermediate, is generally used by the organism at certain levels, hence option c nitrogen gas, ammonium, nitrite, nitrate is correct.

The nitrogen cycle in the biogeochemical cycle converts nitrogen into various chemical intermediates as it cycles into the air, terrestrial, and marine environments.

The nitrogen conversion processes occur through both biological and physical mechanisms. Fixation, ammonification, the first two steps, nitrification, and denitrification are all important processes in the nitrogen cycle.

The bulk of the Earth's atmosphere contains  (78%) majorly composed of atmospheric nitrogen, make the primary source of nitrogen.

Therefore, option c begins with nitrogen gas, ammonium, nitrite, and nitrate in the correct order.

Answer:

I think its A...

Explanation:

Because a cell has to communicate with someone to identify the objects or things that goes inside it.

The ribosomes produce the proteins by communicating with the cell. The correct option is A.

Ribosomes are tiny molecules made up of RNA and related proteins that are responsible for protein synthesis.

Proteins are required for many cellular activities such as emergency repairs and chemical process control.

Ribosomes are found in the cytoplasm or connected to the endoplasmic reticulum.

Ribosomes have two primary functions: message decoding and peptide bond formation.

The ribosomal subunits are two huge ribonucleoprotein particles of variable size that house these two activities.

Each subunit is made up of one or more ribosomal RNAs as well as numerous ribosomal proteins.

Ribosomes communicate with the cell to produce proteins.

Thus, the correct option is A.

Answer:

Placebo effect

Explanation:

People tend to think they've been cured by something even if the something isn't effective, and they might even experience minor symptoms of having been effectively treated. If people know that the drug they're being given is the one being tested, they'll be more likely to experience this effect because it's the drug that the researchers think is going to work. Researchers conduct double-blind studies to prevent bias in the researchers and to prevent the placebo effect from interfering with the results from the test subjects.

Answer:

D. The patients and researchers are not given this information so they cannot be influenced in reporting the effectiveness.

Answer:

Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent.

Explanation:

It looks to me like the pine cones and other pines are in some sort of group of plants. I think this word is called "gymnosperms" which also means a "naked seed". In conclusion, just like other gymnosperms, pine cones reproduce by sexual reproduction

Answer:

White pines reproduce sexually: their reproductive process requires both types of cell division. Because they form haploid gamete cells, meiosis must occur. Because of mitosis, the seeds grow into new plants.Explanation:

mitochondrial DNA analysis

Explanation:

A DNA fingerprint is a laboratory technique that identifies DNA repeat sequences that produce a pattern specific to that individual. Mitochondrial DNA (mtDNA) exhibits several useful features for human identification and for their use in DNA fingerprinting: 1-doesn't undergo recombination, 2-a high copy number, and 3-matrilineal inheritance (i.e., mtDNA is inherited from the mother). It is for these reasons that mtDNA fingerprint analysis has become very useful for human identification.

Action Potential reaches the Axonal terminal

Vesicles filled with neurotransmitters move to the end of the axonal terminal

Neurotransmitters are released into the synaptic cleft

Neurotransmitters attach to the sodium channels on the dendrite.

Sodium channels open

Sodium moves into the Dendrite

Action potential travels through the dendrite

Explanation:

The process of transmission of action potential across a synapse ( a junction between two neurons) begins with the arrival of an action potential from the presynaptic neuron. The steps are given below:

Action Potential reaches the axonal terminal of the presynaptic neuron

Vesicles filled with neurotransmitters move to the end of the axonal terminal of the presynaptic neuron

Neurotransmitters are released into the synaptic cleft

Neurotransmitters attach to the sodium channels on the dendrite of the postsynaptic neuron

Sodium channels open

Sodium moves into the dendrite of the postsynaptic neuron.

For recessive traits to be observed, dominant genes must be absent.

Explanation:

There are 3 possibilities for the genes: AA, Aa, aa.

in both AA and Aa, there is a dominant gene present. If a dominant gene is present, it will always show the dominant trait.

In aa, there is no dominant gene present, and there are only recessive genes. Because of this, the recessive trait is observed!

Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground.

Answer:

Carbon enters the soil through the decomposition of organic material.

Explanation:

Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. That’s why when humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
