▶ Global warming can cause sea levels to rise dramatically. In many places, coastal areas have already been flooded. Global warming could result in wide ranging effects on rainfall patterns, agriculture, forests, plants and animals. Majority of people living in regions which are threatened by global warming are in Asia. A recent climate change report gives us only a limited time to keep the greenhouse gases at the present level. Otherwise, the temperature may rise by more than 2 degrees Celsius by the end of the century, a level considered dangerous.

In sexual reproduction, will an offspring show a recessive trait if just one of its parents has recessive alleles for that trait? Explain your answer.

Answers

Answer:

No, they will not

Explanation:

In this question, we assume that the parents have genotypes of rr and RR (I use "r" out of convenience). If we cross both of these parents, it is impossible for any of the offspring to be rr like the one parent. They would all be heterozygous. If the other parent had a single recessive allele, then it would be possible.

H-E-L-P! ASAP! Describe two ways that plants respond to their environment, giving an example of each. Your answer can include ways that plants respond to seasonal changes, light, gravity, or touch.

Answers

Plants have evolved to respond to critical changes in the environment by either growing their roots, or leaves towards/away from any stimulus. This response, is called a tropism.

For example, The plant's stem and leaves bend toward sunlight. Their roots grow toward Earth's gravity.

Plants have complicated systems to detect and then respond to changes in light, gravity, temperature, and or even physical touch.

Which organism carries out autotrophic nutrition

Answers

Answer:

Autotrophs is the answer

Example : plants

Plants and some bacteria (e.g., cyanobacteria) carry out autotrophic nutrition, synthesizing their own organic molecules using light or inorganic substances.

Organisms that carry out autotrophic nutrition are capable of producing their own organic compounds and energy sources using inorganic substances. One example of an organism that performs autotrophic nutrition is plants. Plants possess specialized structures called chloroplasts that contain chlorophyll, a pigment responsible for capturing sunlight energy.

Through the process of photosynthesis, plants convert carbon dioxide and water into glucose, a form of stored energy. This energy is then used by the plant for growth, development, and other metabolic processes. Additionally, some bacteria and protists are also capable of autotrophic nutrition. These organisms utilize different mechanisms such as chemosynthesis or photosynthesis to synthesize their own organic compounds and derive energy from non-organic sources, such as inorganic chemicals or light, respectively.

What did Allan Savory notice about the lands grazed by wild animals at the Africa Centre for Holistic Management

Answers

Answer:

Allan Savory noticed that grasslands co-evolved with large numbers of migrating ruminants, and therefore are co-dependent on each other's survival. These animals grouped together and constantly bunched due to the predator-prey connection, eat the grasses following the seasons throughout their migration in arid regions (Brittleness scale, of Non-Brittle to Brittle environments).

As they move, they drop nutrient-rich dung and urine, while trampling organic litter (live or dead grasses, leaves, etc) and seeds into the soil. These actions break down materials into the surface, providing more covered soil and keeping materials from chemically decomposing (oxidation, as opposed to the fast biological decomposition that occurs in areas with consistent rainfall(Non-Brittle)). The true testament to his insights of Holistic Management re: grasslands is known as the 4th Key Insight: That time, rather than numbers governs over-grazing or over-trampling.

The important component here is that the time exposed to these animals plays the significant role in whether you have healthy grasslands, not the number of animals exposed to the area of consideration. The amount of "rest" (time) for grasses between eating or trampling is just as crucial as the time in an exposure.

Explanation:

Explained in his book and courses under "Holistic Management", by Allan Savory and Jody Butterfield, and Sam Bingham

illustrate how the self sealing bubble membrane helps to illustrate the passage of molecules through a cell membrane and the property of selective permeability

Answers

Self-sealing bubble membranes help to illustrate the passage of molecules and the property of selective permeability in that they are an example of how something can be semi-permeable and allow only some substances to pass.

When we mention a membrane, we refer to the selective barrier that protects cells from the environment. Within this barrier, lie certain proteins that serve as a kind of "tunnel" for the passage of very specific substances. This, along with a few other mechanisms are what gives a membrane the title of being semi-permeable.

This is because semi or selective permeability is the ability to allow the passage of very specific substances despite being a sealed barrier. Self-sealing bubble membranes share this ability by allowing some substances, like specific gases, to enter the bubble while others will remain on the exterior of the sealed barrier.

why are antibiotics not effective against viruses?

Answers

Answer:

Viruses are different to bacteria; they have a different structure and a different way of surviving. Viruses don't have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat. Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis, or runny noses, even if the mucus is thick, yellow, or green. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.
