what are the two functional parts of a tRNA
Answer: Transfer RNAs are coded by a number of genes, and are usually short molecules, between 70-90 nucleotides (5 nm) in length. The two most important parts of a tRNA are its anticodon and the terminal 3’ hydroxyl group, which can form an ester linkage with an amino acid.

when preparing pure cultures, dilution is necessary for
Dilution is necessary during pure culture preparation to reduce the bacterial load and allow readable colonies to grow.
Dilution of bacteria culture is carried out in comparison to McCfarlan standard so as to have a decent number of bacteria that will not be too numerous or too little to observe the growth of distinct colonies during culture preparation.
Without dilution, colonies may form but may be too numerous to count. Too much dilution may also lead to no growth in the culture plates.

3. What challenges do older generations face?
Answer:
Health problem. As aging occurs, the more weak and unstable the body gets.
Unporportionate generation distribution. Some older generations are larger than the ones that precede it, thus, making it harder to have the proper resources to take care of older generations.
Technology. It is harder for older generations to be up-to-date on technology. This can make it harder for older generations to function in society properly.

Answer:
Precipitation
Explanation:
If it's the graph that I am thinking of, then it is precipitation. This is where raining occurs in he picture.
The biogeochemical cycle where the water circulates from the atmosphere to the Earth surface in a continuous motion is called the water or hydrological cycle.
The process that occurs at location W is:
Option A. Precipitation
The water cycle can be explained as:
The water cycle has four main components that are evaporation. condensation, precipitation and runoff.When an atmospheric substance falls on the ground in the form of rain, snow hails etc. are called precipitation.When the water from surfaces turns into vapours and moves upwards in the atmosphere is called evaporation.The vapours in clouds turn into water droplets ready to fall as rain or snow is called condensation.Transpiration is a plant function in which surplus water is exhaled from the stomata of the leaf.Therefore, the water cycle shows precipitation.

which muscles are also known as the smooth muscles
Answer:
involuntary muscle
Explanation:
Involuntary muscles are those that cannot be controlled by will or consciousness and are frequently associated with organs that contract and relax slowly and regularly.

Answer:
Explanation:
Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era. (See the geologic time scale.) The major divisions of the Mesozoic Era are, from oldest to youngest, the Triassic Period, the Jurassic Period, and the Cretaceous Period. The ancestors of major plant and animal groups that exist today first appeared during the Mesozoic, but this era is best known as the time of the dinosaurs.

https://brainly.com/question/14165885
a) In a food chain, arrows show the movement of nutrients or energy from one organism to another. It refers to the direction of transfer of energy or nutrients from the organism being consumed to the organism consuming it.
b) The producer in the diagrammatic food chain is lettuce, followed by green fly, ladybug, thrush and cat. Producers—also called autotrophs—are living things that can make their own food through photosynthesis or chemosynthesis, the process by which sunlight or inorganic substances are converted into energy-rich organic molecules.
c. Ladybird is the third trophic level of the food chain. The term "trophic level" describes the place an organism occupies in a food chain or web, from where it obtains its food and energy. In this scenario the greenfly is the primary consumer at the second trophic level, while the ladybird is the secondary consumer at the third trophic level. Lettuce is the first trophic level in this scenario (producer).
d.Cat is the third largest consumer in the provided food chain. In a food chain or web, tertiary consumers are those species at the highest trophic level. Typically, they are carnivores that prey on other carnivores or secondary consumers.
e) Sun is the primary energy source that powers the food chain. Most ecosystems get their energy mostly from the sun. As the species consumes and is consumed by other organisms, it is passed along the food chain after being captured by producers (such as plants) through photosynthesis.

What is a lymph node?No lymph nodes exist in the central nervous system. The lymph nodes are more likely to gather in three locations on each side of the body.
The inguinal nodes in the groin, axillary nodes in the armpit, and cervical nodes in the neck are where these sites are found.
The typical lymph node is enclosed by a connective tissue capsule, which divides it into lymph nodules. The lymph nodules, which are dense aggregations of lymphocytes and macrophages, are divided by lymph sinuses.
Therefore, there are several locations throughout the node's perimeter where afferent lymphatics, which carry lymph there from the periphery and enter the node on its convex side, may be found.

How are seeds produced
Answer:
From other seeds
Explanation:
They grow more seeds form the one seed
Answer:
From plant reproduction.
Explanation:
Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. Most, but not all plants, have both male and female parts inside one flower. The stigma is usually in the centre and the stamens, which produce the pollen, cluster around it. The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.

What is the difference between weathering and erosion? (Site 1).
Answer:
Weathering and erosion are natural geological processes that act like rocks and soil on the earth's surface, moving and reshaping the earth. Weathering is the breaking down of rocks into smaller pieces by changing the size and structure of the rocks. The forces of nature are largely responsible for this process. Erosion involves processes such as wind, water flow, and ice movement, which results in change from one place to another.
