all of the following are reasons why friendships are more highly valued by older people in late adulthood than family relationships expect?

Answers

There are no choices but the reason why we tend to value friends as we grow older is because these are bonds that we create on our own. These are people who have been there for us throughout our lives. They are our link with the outside world since they are not our family members. The longer we are friends with others, the deeper that bond becomes.

Crop rotation does all of the following EXCEPT? Choose one answer. a. minimize erosion b. let fields lie fallow c. return nutrients to soil d. organic fertilizer.

Answers

Crop rotation does all the things listed in the options exceptoption d. organic fertilizer.

Crop rotation is a farming practice that involves the systematic planting of different crops in a specific order over time. It offers several benefits to agricultural systems, including minimizing erosion, letting fields lie fallow (rest) to restore soil health, and returning nutrients to the soil. However, crop rotation itself does not involve the use of organic fertilizer. Instead, it focuses on the strategic arrangement of crops to enhance soil fertility and reduce pest and disease buildup.

Therefore, the correct answer is d) organic fertilizer.

Water is drawn upward from the roots through plant tissue to the leaves by

Answers

water exaporates frm the leaves and other parts of the plant above the ground. The evaporation of water from the plant is called ''transpiration''. It occurs mainl through the stomata. However, as quickly as water is lost from the leaves, more water enters the roots and flows up the stem. The water flows up the plant in narrow pipes, rather like capillary tubes. These tubes make up the xylem. The walls of the tubes are made of lignin, which is hard and waterproof. In trees and shurbs the xylem tubes are one of the main components of wood. They do not contain living material and are therefore dead.` Water rises up the stem mainly by being ''pulled'' from above. The ''pull'' is created by the evaporation if water from the leaves. If you stop this by, for example, cutting iff the leaves or blocking the stomata, the flow of water up the stem slows down or stops. The drier the atmosphere, the greater is the rate of transpiration. In very dry wather, water may evaporate from the leaves faster than it is replaced from the soil. The plant then suffers from water shortage. Normally a plant's cells are full of water, and all the cells are pressing against each other within the epidermial covering. This helps to support the plant amd holds the leaves out flat. If a plant runs short of water, the cells lose water and go flabby. The plant then droops. This is called wilting. Plants living in dry places have all sorts of adaptations for not

THE CORRECT ANSWER IS A) CAPILLARY ACTION

What is an advantage of using transgenic bacteria to produce human proteins?

Answers

Transgenic bacteria produce human proteins in a greater amount.

Bacteria are simple organisms with fast reproduction. The bacterial population can double its size every 20 minutes. So, they are very suitable for growing in the culture and for genetic modifications. Nowadays, it is easy to modify bacterial genome to produce desired proteins, such as insulin, human growth hormone, etc. Thanks to its quick reproduction, desired proteins are produced in greater amount for a short period of time.

Calcareous ooze is an example ofA. Terrigenous sediment
B. Bio genous Sediment
C. Hydrogenous sediment
D. Both A and B

Answers

The correct answer is option B, Bio genous Sediment

Reason -

The calcareous ooze is known as biogenous sediment as it has formed from the calcareous microscopic shells of the living organism. These oozes have primarily developed due to the deposition of soft muds in the ocean floor made up of calcium or diatoms or radiolarians.. These biogenous sediments are found in the form of a) mineral calcite and b) aragonite.

Calcareous ooze is an example of bio genous sediment and the correct option is option B.

Bio genous sediments are formed from the remains of marine organisms such as shells, skeletons, and other calcareous or siliceous materials.

Calcareous ooze specifically refers to sediment composed mainly of the calcium carbonate shells or tests of microscopic marine organisms like foraminifera and coccolithophores.

These organisms extract calcium carbonate from the water to build their protective structures, and when they die, their remains settle to the ocean floor, accumulating over time to form calcareous ooze. It is important to note that terrigenous sediments, which originate from land sources, can also mix with bio genous sediments in some areas, creating a combination of both types of sediment.

Thus, the ideal selection is option B.
