wolverine [178]3 years ago
5 0

Answer:

Explanation:

Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another

One reason that atp is a source of energy is that the products of atp hydrolysis have less free energy
Svetlanka [38]
Correct! molecules going through reactions always want to form products that are less in energy so that molecules can be more stable. ATP molecule when made is not very stable and so it is high in energy. So when hydrolyzed, it breaks down to something simple and releases energy and achieves a less free energy (deltaG) state

What ecological factors do you think might come into play when deciding how to time a pulse flow?
UNO [17]

Answer:

- Species inhabiting the river and surrounding areas

- Hydraulic characteristics

- Geomorphology dynamic

- Water quality

Explanation:

Presence of different species: Assay the species inhabiting the area of the river corridor. These species include invertebrates, animals such as fishes, amphibians, reptiles, birds, and mammals, and plants living near the shore and on the floodplain. These species might be affected in some portion of their life cycles by the difference in the river pulse flows. Life stages and population dynamics might be considered of importance when timing the pulse flow.

Hydraulic characteristics: Habitat in aquatic systems varies according to the season and the pulse flow. Depth, velocity, substrate, and instream cover might be considered important factors influencing the presence of different species and their development.

Geomorphology: Refers to the shape of the channel and floodplain. These will depend on the stream velocity, sedimentation, depth, among others. The river geomorphology is in constant change, from season to season. This dynamic also affects the shape of the floodplain and riparian zone.

Water quality: Refers to the difference in sediments, suspended elements, available nutrients, dissolved oxygen, and temperature. All of these affect and influence different forms of life and their evolution through the corresponding cycle stages.

A student conducted an experiment to test the concept of semipermeability of a cell membrane. She has?
alexira [117]

Answer:

diffusion ( osmosis)

Explanation:

Recall that osmosis is the movement of water or liquid molecules from the region of low concentration to the region of high concentration until it's evenly distributed through a semipermeable membrane

so now it depends on the type of solution she use to check the permeability of the cell membrane

aivan3 [116]

The best protection from Haemophilus influenza that causes infant meningitis is administration of conjugate vaccines.

Vaccines are injections administered into body to provide protection. They are based on the principle that prior introduction to weakened or killed from a microorganisms produced natural immunity against it which is remembered by the body by memory cells.

The conjugate vaccines are combination of weak and strong antigens which results in stronger immunity against weak antigens. The conjugate vaccine of Haemophilus influenza comprises polysaccharide of the microorganism. Strong antigen are also known as carrier proteins and in this case are either of tetanus, diptheria toxoid or its mutant toxin of diptheria.
