During the second and third trimesters, pregnant women should gain approximately one pound per week.
Pregnancy is the condition of conceiving a baby wherein a baby is being nourished inside the body of the female (inside the womb of the mother). Weight gain depends in part on your body mass index before pregnancy. Pregnant women usually gain more weight in their second trimesters than in their third trimester. In general, a healthy women needs about 340 additional calories per day during the second trimester. Sweets and fats should be kept to a minimum in the diet. A good consumption of fruit and vegetables should be included because it provides vitamins and minerals needed for the growth of the baby.

How do the layers of the atmosphere help to understand better the dynamics of the atmosphere and its relationship to the hydrosphere and lithosphere?
Answers
There are various layers that make up the atmosphere, and each has distinct properties and functions. Both weather generation and energy transmission take place in the troposphere, which is closest to the Earth's surface.
The stratosphere shields the Earth from damaging UV radiation along with the ozone layer. Most auroras happen in the mesosphere, where meteors burn up. Modern technology is dependent on the thermosphere, where the majority of the Earth's satellites orbit and where communication signals are sent.
The dynamics of the atmosphere and its interactions with the hydrosphere and lithosphere are better understood thanks to these layers. Foreseeing and minimising environmental problems like climate change and preserving our world, it is essential to understand the significance of each layer.

From some observations, a student noticed there are fruit flies flying around and landing on a banana in the kitchen. The student wondered if a certain type of fruit will attract more fruit flies than another. The student set up four jars of the exact same size on the countertop in an area where the light remains the same. They weighed the following fruits and placed 110 grams of each fruit into the jars: banana, strawberry, peach, watermelon. The student had 4 vials of fruit flies (all female, same species, same number) and placed each vial directly in front of jar. The student asked a friend to take the cover off of two of the vials while they removed the other covers simultaneously.

2. What did the Watson and Crick double helix model of DNA structure
explain about this molecule.
Answers
The Watson and Crick double helix model of DNA structure, proposed in 1953, provided a breakthrough understanding of the molecular structure of DNA, which has profound implications for our understanding of genetics, heredity, and molecular biology.
What is DNA structure?The model explained several key features of DNA:
Double helix structure: The model proposed that DNA consists of two strands that are twisted around each other in a helical fashion, forming a double helix structure. The two strands are held together by hydrogen bonds between complementary nucleotide bases (adenine with thymine, and guanine with cytosine), forming base pairs along the interior of the helix. This explained how DNA can have a stable and structural integrity, while also allowing for the replication and transcription of genetic information.
Complementary base pairing: The model explained how the nucleotide bases in DNA (adenine, thymine, guanine, and cytosine) pair specifically with their complementary bases to form the "rungs" of the DNA ladder. This complementary base pairing mechanism ensures that the genetic information stored in DNA is accurately replicated and transmitted during cell division and protein synthesis.
Antiparallel orientation: The model revealed that the two strands of DNA in the double helix are oriented in an antiparallel manner, meaning they run in opposite directions. This orientation allows for the formation of hydrogen bonds between the complementary base pairs, and it has important implications for DNA replication and transcription processes.

Explain how our body systems work together to get oxygen into and around our body
PLS DONT COPY AND PASTE THE ANSWER FROM THE INTERNET
Answers
The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.
How Oxygen from the air is absorbed?Oxygen from the air is absorbed into the bloodstream through the lungs. When it reaches the lungs, the function of the cardiovascular system begins, since that is where the non-oxygenated blood is oxygenated and returns to the heart.
When in the cardiovascular system, the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy. These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood.
O2 and CO2 are constantly circulating and passing from one medium to another, so much so that O2 passes, along with other gases, from the atmosphere to the airways, entering through the nostrils and driving through the larynx, trachea, source bronchi, terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli.

Select the five assumptions of the Hardy-Weinberg equilibrium that must be met to keep allele frequencies from changing.
No natural selection occurs.
Mating is random.
The population is large.
No mutations occur.
There is no migration into or out of the population.
Answers
According to the Hardy-Weinberg equilibrium, if no unfavorable influences exist, genetic variation in a population will remain stable from one generation to the next.
What is Hardy Weinberg equilibrium?The law predicts that genotype and allele frequencies will remain constant because they are in equilibrium when mating is random in a large population with no disruptive factors.
Many factors, including mutations, natural selection, nonrandom mating, genetic drift, and gene flow, have the potential to upset the Hardy-Weinberg equilibrium. For instance, mutations introduce new alleles into a population, disrupting the balance of allele frequencies.
Similar to nonrandom mating, natural selection alters gene frequencies, which upsets the Hardy-Weinberg equilibrium. This happens because specific alleles influence or impair reproductive success.
Therefore, According to the Hardy-Weinberg equilibrium, if no unfavorable influences exist, genetic variation in a population will remain stable from one generation to the next.
