Approximately 10% of the available energy is passed from organisms at one trophic level to organisms at the next trophic level. This is known as the 10% rule or the 10% energy transfer efficiency.

Energy flows through trophic levels in an ecosystem starting with producers (plants or algae) that convert sunlight into chemical energy through photosynthesis. When herbivores consume these producers, only a fraction of the energy stored in the plants is assimilated into their bodies, while the rest is lost as waste or used for metabolic processes like respiration. This assimilated energy becomes available to the next trophic level.

As energy moves up the food chain, similar inefficiencies occur at each level. Carnivores that consume herbivores receive only about 10% of the energy stored in their prey. This pattern continues as energy is transferred to higher-level predators.

The low energy transfer efficiency can be attributed to several factors. First, organisms expend energy for basic metabolic processes, such as respiration, movement, and growth, which reduces the energy available for transfer. Second, energy is lost as heat during these metabolic processes. Additionally, not all parts of an organism are consumed or digested by predators, resulting in energy losses through waste.

Answer:

Thus during metaphase of mitosis, each chromosome (i.e., each chromatid pair) will contain two molecules

Explanation:

double stranded DNA (one molecule per sister chromatid). The following diagram depicts the behavior of one homologous pair of chromosomes during mitosis.

Six DNA molecules are there in three pairs of homologous chromosomes. This is because each homologous chromosome will contain two molecules of double-stranded DNA.  

Homologous chromosomes may be defined as two chromosomes of the same length, position, and structure one inherited from the father's side and the other from the mother's side.

The amount of genetic material may vary from phase to phase of the cell cycle. But at the time of metaphase during mitosis, each chromosome will possess two molecules of DNA.

Therefore, Six DNA molecules are there in three pairs of homologous chromosomes.

Answer:

The bird has a narrow beak that is longer than the length of its head.

Explanation:

-The beak is long and thin, which helps it dip into the flowers to sip nectar (a sugary fluid the hummingbird uses for food).

None of the interest groups mentioned opposed the U.S. Clean Water Act. In fact, the Clean Water Act was passed with broad support from a variety of stakeholders, including environmental groups, industry, and government agencies.

The Clean Water Act (CWA) is a federal law enacted in 1972 with the aim of regulating and protecting the nation's waters from pollution and contamination. The CWA established a framework for controlling and limiting the discharge of pollutants into navigable waters, including rivers, lakes, and coastal areas, and set water quality standards to ensure that waters are safe for human use and aquatic life.

The Act provides a regulatory framework for permitting discharges of pollutants, sets water quality standards for contaminants, and establishes a program for regulating the discharge of pollutants from stormwater runoff. The CWA has been amended several times to strengthen its provisions, and it remains a critical tool for protecting water resources and public health in the United States.

A myocardial infarction comprises a series of changes in the cardiac tissue that originate when there is an inadequate blood flow to the heart muscle or a coronary artery becomes blocked.

It is characterized by the sudden appearance of a picture of ischemic suffering (lack of irrigation) to a part of the heart muscle produced by the acute and total obstruction of one of the coronary arteries.

It is recognized by the sudden appearance of the characteristic symptoms of intense pain in the chest, in the precordial area and a feeling of general malaise.

Answer:

Water helps the kidneys remove waste from your blood through urine. Water also helps keep blood vessels open, which lets blood flow through easier, letting the blood remove its waste through the kidney more efficiently.

Explanation:

Answer:

It helps in Osmoregulation and removal of excess liquid from the body.

Explanation:

It regulates fluid balance by excreting excess amount of water as urine while retaining the necessary amount of water in the body that is essential for living.

Osmoregulation - the process of maintaining salt and water/osmotic balance across membranes within the body.

The fluids inside and surrounding cells are composed of water, electrolytes, and non-electrolytes.

Answer:

heat loss, energy for cellular process: transpiration, other forms of water, oxygen, carbon dioxide loss

Explanation:

The energy received by the Oak leaves which did not contribute to the synthesis of biomass may be used for or produced as heat loss, energy for cellular processes such as transpiration, other forms of water, oxygen, or carbon dioxide loss.

The material from previously living organisms known as biomass is utilised to produce bioenergy. Examples include wood, wood byproducts, energy crops, agricultural waste, and organic waste from commercial and residential sources. The main biomass energy source nowadays is wood and wood waste.

Renewable organic material from plants and animals is known as biomass. Up until the middle of the 1800s, biomass accounted for the majority of the entire yearly U.S. energy consumption. Biomass is a popular fuel in many nations, particularly for heating and cooking in underdeveloped nations.

Thus, the energy received by the Oak leaves which did not contribute to the synthesis of biomass may be used for or produced as heat loss, energy for cellular processes such as transpiration, other forms of water, oxygen, or carbon dioxide loss.

40 chromosomes would be found in the sperm produced by heat same squirrel

40 chromosomes would be found in the sperm produced by heat same squirrel.

A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibres in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.

The highest possible level of DNA and protein organisation is seen in chromosomes. Chromosomes' primary job is to carry DNA and pass genetic material from one generation to the next. Cell division involves the critical function of chromosomes. They guard against tangles and damage to the DNA.

For above given example, if 20 chromosomes are present in skin cells, then the squirrel will have 40 chromosomes in the sperm cells.

Thus, 40 chromosomes would be found in the sperm produced by heat same squirrel.

Answer:

They hibernate in winter and usually breed in spring.

Explanation:

The percentage of moths in the natural population that was white in 1962 is : 4%

Hardy-weinberg equilibrium states that the sum total of all the genes of an individual in a population is constant when the disturbing factors such as genetic drift does not occur

p² + q² + 2pq = 1

Applying the equation below

p² + q² + 2pq = 1

p = frequency of dominant allele

q = frequency of recessive allele

q² = frequency of h0m0zygous recessive genotype

p² = frequency of h0m0zygous dominant genotype

From the graph

Frequency of G allele ( i.e p ) = 0.8

percentage of white moths = q²

Note : p + q = 1  ---- ( 1 )

Insert value into equation ( 1 )

0.8 + q = 1

therefore ; q = 0.2

Hence the percentage of white moths = ( 0.2 )² = 0.04

                                                                               = 4%

Hence we can conclude that The percentage of moths in the natural population that was white in 1962 is : 4%
