Mention the function of oveary ,ovduct and utterus in the female reproductive system. how essential materials are supplied for the development of foetus?
Answer:
- The ovary is the female organ that produces the female gametes
- The oviducts are tubes that extend from the ovaries to the uterus
- The uterus is an organ that acts to nourish and house a fertilized egg until the fetus is delivered
- Materials are supplied by the mother's placenta
Explanation:
The ovaries are the female gonads that function to produce and release female gametes (i.e., oocytes) into the reproductive tract. These organs are also in charge of producing female hormones (e.g. progesterone). The oviducts, also known as fallopian tubes, are a pair of tubes that extend from each ovary to the top of the uterus. The uterus is a thick muscular organ of the female reproductive system that nourishes and houses the embryo and fetus. Finally, materials such as oxygen and nutrients pass from the mother's bloodstream through the placenta which is connected to the fetus by the umbilical cord.

The Gulf Coast Toad, Mexican Treefrog, and Couches Spadefoot Toad are all common species of amphibians found in the central Texas area. Why is having a scientific name for each one important? a. If some of these go extinct due to climate change their names will not have to be changed. b. It allows all organisms to be placed into several varieties of taxonomic ranks. c. To make naming and grouping of all organisms standard across the world. d. If new amphibians are found the current taxonomic rank will not have to change.
Answer:
b. It allows all organisms to be placed into several varieties of taxonomic ranks.
Explanation:
A scientific name is important for every species because it helps to avoid confusion created by common names of two or more species or organisms. In every region there is a name for an organism which causes problem so the scientists suggest that there must be a naming system which is used all over the world so they choose a dead language to giving scientific names to the organisms present all over the world for easily recognition.

Explain the four factors that interact to result in evolution.
Answer: Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.

What is evolution?Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.
Moreover, evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.
Hence, evolutionary processes depend on both changes in genetic variability and changes in allele frequencies over time.

A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. After testing each fertilizer on two different plants for one month, his data led to the conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials because O she did not believe the new formula helped plants grow better than the old formula. O it was necessary to see data from more plants before the conclusion could be accepted. O it was necessary to have tested the fertilizer on different kinds of plants. O she thought he should test additional fertilizer formulas on the same two plants.

How does a region’s latitude impact its climate? What role does the sun play on an area’s climate?
Answer:
Places with latitudes closer to the Equator have hotter climates. Places with latitudes closer to the Poles have colder climates. This happens because the Sun's rays hit them more or less directly.
The Sun powers life on Earth; it helps keep the planet warm enough for us to survive.
The latitude of a region influences its climate, and the sun plays an important role in the area's climate because the more the area receives close sun rays, the warmer it is, and the less the area receives close sun rays, the cooler it is.
What is the significance of the latitude in terms of temperature?Latitude has a significant impact on temperature determination because the closer an area is to the equator, the more sunlight it receives, and thus the warmer it is; whereas in Arctic regions, the area is farther from the equator and thus receives less sunlight.
Hence, the latitude of a region influences its climate, and the sun plays an important role in the area's climate because the more the area receives close sun rays, the warmer it is, and the less the area receives close sun rays, the cooler it is.

What is permutations?
Simplistically, a permutation is just the number of ways that we can arrange any number of objects in a set of things.
EXPLANATION:Here's an example:
Suppose I have three objects A, B and C, and I want to arrange them in all possible ways.
Well, we could have
A B C
A C B
B A C
B C A
C A B
C B A
Note that this is just 6 ways.
In mathematics, we often express the number of possible arrangements of N objects as N!.. the "!" is known as a "factorial."
➥ In the above example, we have 3! ways of arrangement = 3*2*1 = 6.
➥ Then, the number of ways to arrange 4 objects in a set is just 4! = 4*3*2*1 = .24.
➥ And the number of ways to arrange 5 objects in a set is just 5! = 5*4*3*2*1 = .120. Etc.
Take a moment to examine these images of cells and their surrounding membranes. You already know that the cell membrane protects the cell from the external environment and controls what substances enter and exit the cell. As you study the pictures, consider the following questions: Which of the two cells do you think is more efficient at transporting materials through the cell? Why?
Answer:
The bigger cell would be more efficient at transporting because the surface area of the cell membrane is larger. This will allow cellular transport to occur at a faster rate, compared to the other cell.
Answer:
The bigger cell is more efficient at transporting because the surface area of the cell is bigger which is good for transporting

A. Carbon Dioxide
B. Oxygen
C. Lead
D. Nitrogen
The pollutants associated with the high tech-gadgets or e-waste include mercury, lead, cadmium, etc. So the correct answer is option C.
An electronic device that has reached the end of its usable life cycle is called as the electronic waste or the e-waste. The electronic waste contains a lot of toxic compounds inside them and should be handled carefully because this e-waste releases the toxic pollutants in the environment which can cause air pollution and also has an impact on respiratory health.
Burning of e-waste can release fine particles (pollutants) into the enviroment which can cause chronic diseases and cancers as well.
