Answer:
During the process of cellular respiration, carbon dioxide is given off as a waste product.
This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates.
Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.
All of the following are true about thymine dimers EXCEPT: the type of repair that is done to fix them is called nucleotide excision repair they are caused by UV radiation damage that fuses thymines that are next to each other on the same strand individuals with xeroderma pigmentosa (XP) are unable to repair this type of DNA damage, leading to cancer cell development they are caused by UV radiation damage to thymines that are opposite each other on different DNA strands
Answer:
Option 4, they are caused by UV radiation damage to thymines that are opposite each other on different DNA strands
Explanation:
Thymine dimer is formed on adjacent thymine and hence they lie next to each other on the same strand. They do not lie on strand that are opposite of each other on different DNA strand.
Hence, option 4 is correct
Producers, consumers, and decomposers play important roles in the environment. Are there any organisms that would not fall into one of these categories? Explain your answer.
Answer:
No, there are no organisms that will not fall into these categories
Explanation:
Living organisms interact with one another in their natural environment in order to ensure that energy needed for their metabolic activities is obtained. To do this, each organism plays different or specific roles. The roles that every organism must fall into are as follows:
- Producers are groups of organisms that have the ability to synthesize their own food using light (photosynthesis) or chemicals (chemosynthesis). Examples are green plants, algae, some bacteria etc.
- Consumers- These are organisms that lack the ability to synthesize their own food and hence depend on other organisms for their energy source. Consumers can either be herbivores (eat plants) or carnivores (eat flesh) etc. Examples are all animals etc.
- Decomposers- These are organism that have the ability to breakdown dead organisms into organic matter, thereby, adding nutrients back to the soil. Examples are fungi, bacteria, earthworm etc.
Based on this explanation above, no organism will not fall into any of these three categories. Some can even occupy two roles.
SLO-4.2. Within all tissues in the body, there are stores of undifferentiated cells that can become any specialized type of cell in that tissue for the purpose of growth and healing. Today, Regenerative Medicine is trying to employ these cells to replace tissues that have been destroyed by disease and trauma, such as spinal cord injuries. What are these cells
Answer:
These cells are stem cells.
Explanation:
Stem cells have not specialized to be in a specific tissue and have a particular function yet. They are the cells that give all the different cell types that our body has. In other words, they can become any cell type that the body needs. We call them pluripotent cells because they have the potential of becoming any specialized cell.
Scientists use stem cells in tissue or organ regeneration due to the pluripotential that they have.
A big, powerful male gorilla is much more likely than a smaller, weaker
gorilla to become the population's silverback, the pack's leader who mates
far more than the other males of the group. The pack leader will, therefore,
father more offspring, who share half of his genes, and are thus likely to also
grow bigger and stronger like their father. Over time, the genes for bigger
size will increase in frequency in the population, and the population will, as a
result, grow larger on average.

In the logistic growth model, as a population approaches the carrying capacity, what happens to its growth rate?
A
becomes exponential
B
doubles
C
increases
D
slows to zero
In the logistic growth model, as a population approaches the carrying capacity, the growth rate of the population will slow down to zero. Thus, the correct option is D.
What is Logistic growth model?The logistic growth model is a parameter which represents the rate at which the population would grow if it were unencumbered by the environmental degradation. A second parameter, that is K, represents the carrying capacity of the system of species which are being studied.
In logistic growth, a population's per capita growth rate gets smaller and smaller as the population size when it approaches a maximum imposed by the limited resources in the environment, known as the carrying capacity (K). Exponential growth model produces a J-shaped curve, while logistic growth produces an S-shaped curve.
Therefore, the correct option is D.

If a pet has to survive without your care, how would its diet change? Write your ideas on the lines below. Read about how organisms get food and energy in their environment
Answer:
rather than consuming "pet food" that contains all proper nutrients required your pet would being to scavenge for food wherever they could find it. Survival instincts would kick in and they would eat whatever they could find. Depending on food availability, loss of muscle mass is a possibility.
Explanation:
If my pet is to survive without me, its diet will change. First of all, he will not get food, so how is it possible for a living being to survive without food. It will get skinny and starve to death after a few days.
What is Diet?Diet is defined as the sum of food that is consumed by a person or other organism. The term diet refers to the use of a specific intake of nutrition for health or weight-management reasons. Humans are omnivores so, every culture and every individual has some food preferences or some food taboos.
It is essential for good health and nutrition protects you from many chronic non-communicable diseases like heart disease, diabetes and cancer. Eating a variety of foods and consuming less salt, sugar, and saturated and industrially produced trans-fats are important for a healthy diet.

Drag each label to the correct location on the table. Sort the observations based on whether they are quantitative or qualitative.
Answer:
Qualitative observations are those that cannot really be counted or measured by empirical figures, but are rather described by the features they have such as their color or taste.
Quantitative observations can be measured and counted by empirical figures i.e. numbers such as age and temperature. Number operations such as addition can be performed on them as well.

The original base sequence of DNA is : CAG TTA CCA. If the amino acid sequence that results from translation of this DNA base sequence is: valine-tyrosine-glycine, what mutation occurred in the DNA? Explain
A. An addition mutation occurred
B. A deletion mutation occurred
C. A substitution mutation occurred
D. A mutation did not occur.
C
I think substitution, because the original translation of the original base sequence is glutamine-leucine-proline. The base sequence for valine-tyrosine-glycine is: GT# TA# GG# . of course the last codon is unclear, but the first two gives us enough to know too much change happened for a simple addition or deletion mutation. The bases were completely switched out, therefore it is a substitution mutation. I attached a codon chart.
