<u>Answer:</u>

<em>A plasma membrane is the cellular structure that makes it possible for a cell to differ structurally and biochemically from its surroundings. </em>

<u>Explanation:</u>

<em>Plasma membrane</em> is the surrounding of all the cells. The function of plasma membrane in a cell is to regulate the incoming and outgoing elements from the cell.

<em>Phospholipid bilayer</em> is the main composition of plasma membrane. It makes the cell different from each other structurally as well as makes the cell different in <em>chemical composition </em>too.

Answer:

Larger habitats support populations with higher carrying capacities. Higher quality habitats support populations with higher carrying capacities. There is no difference in population growth rate between large and small habitats. Some major threats to biodiversity are: Habitat destruction/Deforestation, Introduced and invasive species, Genetic pollution, Over exploitation, Hybridization, Climate change, Diseases, Human overpopulation. If abiotic or biotic factors change, the carrying capacity changes as well. Natural disasters can destroy resources in an ecosystem. If resources are destroyed, the ecosystem will not be able to support a large population. This causes the carrying capacity to decrease.  

Carrying capacity could be reduced if each individual within the species consumed less from the environment. Think about humans: if every human needs a four car garage and a large house, the planet can sustain fewer humans than if each human lived in a studio apartment and traveled using a bicycle. It would take 1.75 Earths to sustain our current population. If current trends continue, we will reach 3 Earths by the year 2050. It is beyond dispute that the modern industrial world has been able to temporarily expand Earth's carrying capacity for our species. As Nordhaus points out, population has grown dramatically (from less than a billion in 1800 to 7.6 billion today), and so has per capita consumption. Historically, habitat and land use change have had the biggest impact on biodiversity in all ecosystems, but climate change and pollution are projected to increasingly affect all aspects of biodiversity. Sustainable agriculture practices support integrating biodiversity in various ways including in terms of diversity of crops, traditional agriculture techniques to control pests and increase productivity as well as ensuring that farmed land is made up of a diverse mix of grazing land, crop land, orchards, wetlands and more.

Which characteristics must an object possess in order to be considered allve?
rosijanka [135]

Answer:

hi here is your answer hope it helps

Explanation:

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, homeostasis, energy processing, and evolution. When viewed together, these characteristics serve to define life.

Select all that apply.
professor190 [17]

The right answer is B and C.

For proposal C, I will give you an example, that of an autosomal recessive disease. If a parent is heterozygous for an allele causing an autosomal recessive disease (due to a mutation), it may be that it transmits the allele to its descendence, as it may not be able to transmit it (since in one heterozygous subject, not all of its gametes carry the mutated allele) and thus the mutation will no longer be copied through the generaitons.

Each individual is genetically unique. Its genes are distributed along chromosomes contained in the nucleus. Mutations can lead to the appearance of different versions of genes: alleles. A diploid individual has two copies of each gene, which may be identical or different alleles. Mixing during sexual reproduction partly explains the genetic diversity of individuals.
