Which of these is true of fetal development by the end of the third trimester?
A. The placenta is absorbed by the uterus.
B. The fetus can survive outside the uterus.
c. All development is complete.
D. All growth is complete.
Answer:
B. The fetus can survive outside the uterus.
Explanation:
The third trimester starts in the wekk 28 (month 7 ) of fetal development and lasts until the birth pf baby, that is around week 40 (month 9) of pregnancy.
There are several changes occur in the thrid trimester of the fetal development such as hearing and visual has developed and the internal organs including the heart, lungs, intestines and stomach has developed enough.
So, at the end of fetal development of the third trimester as all the body organs have grown and developed, a fetus can survive outside the uterus.
The correct option is B.
Answer:
Option B
Explanation:
During the third trimester, the fetus continues to grow in weight and size however the body systems finish maturing. In fact, both mother’s body and the fetus continue to grow and change. Lungs, brain and kidneys keep maturing. Fetus position itself head-down and is 6 to 9 pounds in weight. Skull bones are soft but fetus become able to suck its thumb and cry. By 38 to 40 weeks, the lungs have matured fully . The end of third trimester marks the period when the fetus is ready for delivery. Hence option B is the correct answer

Found: A Plant-Eating Spider. Spiders are meat-eaters. Until recently, scientists thought that was true for the roughly 40,000 spider species in the world. Now, researchers have discovered a spider that eats mostly plants. Bagheera kiplingi, a jumping spider, lives in Central America and Mexico. It nests in the leaves of acacia tree. Scientists have long known that ants live in these trees. The ants eat the tree’s little yellow vegetables. But scientists had no idea that the spiders eat the vegetables too. Is competition likely to occur between the Bagheera kiplingi and ants living in acacia trees? Support your answer. *
Answer:
Yes, competition is likely to occur
Explanation:
Competition is an ecological interaction between organisms of the same or different species, resulting in the detriment of one of the organisms. Competition is generally caused when organisms in an ecosystem occupies the same niche i.e. they rely on the same ecological resource, which could be food, mate, space etc.
The case described in this question involving a Bagheera kiplingi (jumping spider) and acacia ants will likely result in competition because they both occupy the same habitat and feed on the same food (vegetable plant). The two organisms will have to compete for this limited resource, hence, it is regarded as an INTERSPECIFIC COMPETITION because it involves two different organisms.

Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.
What is soil erosion?The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.
Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.
Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.
In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.

The diagram shows a normal red blood cell and a shrunken red blood cell, both of which are in salt water.
In which direction did the water move to make the red blood cell shrink? Why did water move in that direction?
Answer:
The red blood cell shrank because water moved out of the cell, which happened because the concentration of salt outside the cell was greater than the concentration of salt inside the cell. Because the salt molecules take up space in the salt water, the concentration of water outside the cell was less than the concentration of water inside the cell. Therefore, water moved out of the cell from the area of high concentration to the area of low concentration, causing the cell to shrink.

How does digitizing images make it easy to transmit images?
Answer:
Digitizing means converting something into digital form.
Digitizing image means converting any image into digital format and the image will be organized into bits or pixel. The bits or numbers are then processed by a computer and output is generated as visible-light image,
There are several advantages of digitizing images and one cam easily tansmit images:
A digitizing image is saved in pixel or square, when computer processes teh pixel or square it gives the image. More number of pixel means better quality of image.The digitized image can be easily send or share in compressed form which takes less space in computer and without affecting quality.Digitized images helps to easily transmit real image without any blur effect.Hence, digitizing image is common now a days to transmit images of better quality in easy way.

To the first group, you do not add fertilizer and the plants are watered with plain water. The second and third groups are watered with two different brands of fertilizer. After three weeks, you measure the growth of each plant in centimeters and calculate the average growth for each type of fertilizer. Identify the independent variable, dependent variable, control group, and experimental group from this experiment?
Answer:
Control group - the plant group which has not received the fertilizers treatment.
Experimental group- the groups treated with different varieties of fertilizers.
Independent variable- amount of water and fertilizers
Dependent variable- growth of plants

The woolly mammoth was a relative of elephants that lived in the far north. There is much debate in the scientific community about what caused the extinction of mammoths. Climate models show that changing weather patterns stressed mammoth populations. Hunting by humans may have also reduced populations. The youngest mammoth remains on a continent are 10,000 years old.
A group of scientists is trying to bring mammoths back by modifying elephant DNA. The new animals would have a mixture of elephant and mammoth genes. What will be the effect of the new genes?
A. The new genes will produce different proteins.
B. The new genes will prevent DNA replication.
C. The new genes will require gene therapy.
D. The new genes will not have RNA.
Answer:
C
Explanation:
Because when new genes are created they won't be able to adapt easily, so they will require gene therapy so they will be able to adapt easier.
Hope this helps you. :)
Have a good day!
The new genes will produce different proteins. Therefore, option (A) is correct.
By modifying the DNA of elephants to include mammoth genes, the scientists aim to introduce genetic variations that were present in the woolly mammoth. These genetic variations would result in the production of different proteins compared to the proteins produced by elephants.
Proteins are essential molecules that perform a wide range of functions within living organisms, including structural support, enzymatic activity, and regulation of biological processes. Therefore, the introduction of new genes from mammoths would lead to the production of different proteins, potentially affecting various traits and characteristics of the modified elephants.
