The system that maintains the human species from generation to generation is the REPRODUCTIVE system. This system is responsible for producing male and female gametes.
The reproductive system is an organ system by which humans produce male (sperm) and female (ovule) gametic cells.
Male and female gametes fuse during fertilization to produce a diploid zygote that develops into an adult individual.
In women, the reproductive system is composed of the ovaries, uterus, fallopian tubes, cervix, and vagina.
In men, the reproductive system includes the testes, prostate, and penis.

A certain DNA molecule contains 22% of the nitrogenous base Adenine. What complimentary base would be found to bind to Adenine and what concentration would the base be measured in when studying the molecule?
Answer:
Adenine would pair with complimentary base thymine and have a concentration of 22%.
Explanation:
Since purines pair with a pyrimidine, adenine would have to pair with either cytosine or thymine. Cytosine only binds with guanine leaving thymine. Since thymine pairs with adenine, there must be equal amounts in the molecule, therefore it is 22%.
5. Juan’s cell phone company charges $35 a month for the phone service plus $0.50 for each text message. How many text messages does Juan send in a month if his bill was $52? plz help its due today
Answer:
Juan sent 34 text messages in a month
Explanation:
You have to create an equation for your problem!
t = text messages
The equation below represents the charge for Juan's cell phone usage
35 + 0.50t =$
Substitute 52 for "$" since that is the amount of the bill sent to Juan for a particular month.
Solve!
35 + 0.50t = 52 ---- subtract 35 on both sides
0.50t = 17 ----divide 0.50 on both sides
t =34

Answer:
The answer is that they contain exogenous or modified DNA.
Explanation:
When you say genetic, you are referring to genes. And as we know, genes are made up of DNA. So if you modify the genes, you are also modifying the DNA of that plant. Also, to make plants more durably, survivability, or better, farmers often add genes to the plants.
Place the rock layers in order from oldest to youngest with the oldest layer on the bottom and the newest layer on top. Remember that extinction is forever. Once an organism disappears from a layer, it will not reappear in a newer layer. Take a screenshot of your results to include in your Lab Report.
The organization of the rock layers from bottom to top is 3, 4, 8, 5, 6, 2, 1, and 7.
As shown in the image there are different layers of rock disorganized, each containing several specific species of organisms.
To organize them, it was necessary to analyze the organisms that were becoming extinct and what arose in each layer. According to this analysis, the layers were organized in the following order from oldest to newest:
Layer 3 (organisms 1, 2, and 3)
Layer 4 (organisms 1, 2, 3, 4, and 5)
Layer 8 (organisms 1, 2, 3, and 4)
Layer 5 (organisms 1, 2, 3, 4, 6, and 7)
Layer 6 (organisms 6 and 7)

All of the following will help the skin to fight infection but one. Which of the following will have little effect on the skin's ability to fight infection? Group of answer choices More tight junctions between keratinocytes of the stratum corneum. Greater production of melanin. Increased secretions of defensins from skin cells. Greater production of keratinocytes resulting in more layers of the stratum corneum.
In order for the skin to fight off infection more efficiently and of the options listed, the correct choice would be for the skin to secrete more defensins.
Keratinocytes are the cells that constitute the epidermis. They are the most dominant cell type in this region and function to create and maintain this barrier. Though this barrier that they create does in fact aid in avoiding bacterial infection, it does little to fight off an already existing infection.
The correct answer is for the skin cells to secrete a greater number of defensins. These are small cationic proteins which are known as "Host Defense Peptides". What this means is that these defensins will either have direct anti-infection properties, or they will act as signals for the immune system.

What will be happen when cell placed in hypertonic solution?
(1) Shrinking of cell
(2) Swelling of cell
(3)No changes in size
(4) Endosmosis
Answer: If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. Image credit: Mariana Ruiz Villareal.

Which of the following describes when the cell leaves the cell cycle and no longer divides?
(1 point)
O interphase
O senescence
o differentiation
O mitosis
When the cell leaves the cell cycle and no longer divides, it enters the quiescent phase.
The quiescent phase is also known as G0 phase. It is a phase in the cell cycle where cells that have no need to divide enter a perpetual resting phase until they are signalled to divide.
Once they get a signal to divide, they move from the G0 phase to the G1 phase and then proceed normally with the cell cycle. For example, cells of the neurons in humans have no need to divide unless on special occasions. Such cells stay in G0 phase perpetually.

Protecting marine life from overfishing is a type of sustainable practice and is therefore denoted as option D.
What is Sustainable practice?These are the activities which are required for the maintenance and preservation of the qualities which are present in the environment and examples of such qualities include air, animals etc.
This type of practice also ensures that the activities done by humans don't affect other components of the ecosystem in a negative manner. Special attention is paid to the adverse effects which could occur such as extinction, pollution etc thereby averting them.
In this scenario, protecting marine life from overfishing helps to prevent extinction of the species which is therefore the reason why it is a sustainable practice.

The fossils that scientists find and study today formed thousands to millions of years ago. But, you can simulate the process of fossilization. Follow these steps to model a fossil:
Line the inside of the plastic container with plastic wrap.
Let the ends of the plastic wrap hang out of the container. The overhanging ends will allow you to more easily lift out your formation when it’s complete.
Pour four inches of water into the container. Use a ruler to measure the correct depth.
After adding the water, add two inches of sand.
Spread the twigs and leaves in a thin layer on the top of the sand.
Stay safe! Use gloves when handling the leaves and when checking the inside of your model during the weeks to come. Wash your hands and gloves when you are done.

After assembling the materials, record your observations. Describe what the setup looks like and the color of the leaves and twigs. Predict what changes will take place over the next few weeks.
