using the diagram, explain in terms of cell division how the white Pine reproduces sexually.
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:

Explain how mutations cause cancer cells.
Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Explanation:
Answer:
Disclaimer: I haven't had a proper science class in ages and I forgot most of the terms. I probably don't have the correct answer that you're looking for, but this is to the best of my ability.
Mutations in cells can cause cancer as it will compete with other cells for energy and space. It will continually multiply/rapidly grow and can't be rid of as its internal system of apoptosis was hindered during the mutation. Mutations can occur due to damages in the DNA.
What does your body do with the waste it does not need?
Answer:
Hello there, Goodmorning and God Bless...Here is your answer to your following question:
Water, some undigested pieces of food and general body waste are now going to the lower intestine. Bacteria, then join in to break up some of this and release some more nutrients including water and some vitamins that the body consumes.
Explanation:
I did not copy off of google y'know U3U
Can in also get brainlest too ;)
Explanation:
You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

What needs to happen for recessive traits to be observed in an organism?
Answer:
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!

There are thousands of different
proteins being produced within the
cell. How does a cell 'know' which
proteins to produce?
A. The ribosomes produce the proteins by
communicatiing with the cell.
B. The DNA segments code for different protein
production.
C. All proteins are the same.
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.
What are ribosomes?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.

Which of the following is the correct order for the nitrogen cycle beginning with nitrogen gas?
a nitrogen gas - nitrate — ammonium - nitrite
b nitrogen gas - nitrite -nitrate - ammonium
C nitrogen gas - ammonium - nitrite - nitrate
d nitrogen gas - ammonium - nitrate - nitrite
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.
What is the nitrogen cycle?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.

In double-blind studies neither the test subject or the researcher knows who was given the drug and who was given the control. Why are these studies effective for testing a drug that may elevate mood and relieve feelings of depression?
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.

Put the following statements about a synapse in the correct order.
= Vesicles filled with neurotransmitters move to the end of the axonal terminal
= Neurotransmitters attach to the sodium channels on the dendrite.
= Action Potential reaches the Axonal terminal
= Sodium channels open
= Neurotransmitters are released into the synaptic cleft
= Sodium moves into the Dendrite
= Action potential travels through the dendrite
Answer:
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.
Action potential travels through the dendrite towards an effector or another neuron.
Which DNA fingerprinting technique examines the length variation of DNA repeat sequences in human DNA? variable tandem repeats analysis polymerase chain reaction analysis Y chromosome analysis mitochondrial DNA analysis
Answer:
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.
