Explanation:

Over 97 percent of the earth's water is found in the oceans as salt water. Two percent of the earth's water is stored as fresh water in glaciers, ice caps, and snowy mountain ranges. That leaves only one percent of the earth's water available to us for our daily water supply needs.

Which process produces a greater number of offspring?
chromosome duplication
asexual reproduction
gamete formation
sexual reproduction

Answers

Answer:

asexual reproduction

Explanation:

Sexual reproduction produces a greater number of offspring compared to asexual reproduction, chromosome duplication and gamete formation.

What is the involvement in sexual reproduction ?

This is because sexual reproduction involves the combination of genetic material from two parents, resulting in offspring that have a unique genetic makeup.

This increases the number of possible genetic combinations and thus the number of offspring produced. Chromosome duplication and gamete formation are involved in the process of sexual reproduction, but neither produces offspring by itself.

Chromosome duplication is the process by which one cell splits into two identical cells, each with the same genetic material. Gamete formation is the process by which reproductive cells such as sperm and eggs are formed.

These cells then combine during sexual reproduction to form a new organism. Asexual reproduction, on the other hand, involves a single organism producing offspring that are genetically identical to itself. This means that the number of offspring produced is limited compared to sexual reproduction.

Then the bottom of the circle would be nonliving beings, either decomposed plants or animals that bring nutrients to soil, or dead ones that we eat. This cycles through until the energy is rereleased through heat. Therefore the top right would be heat energy, every living thing on earth creates gradual amounts of heat.

Answers

Answer:

5' cap

Explanation:

In eukaryotes, the 5′ end of mRNA in eukaryotes is modified (i.e., capped) with a guanine nucleotide which is connected to mRNA via 5´→ 5´ triphosphate linkage. The five-prime cap (5′ cap) is denoted as 7-methylguanylate cap (m7G) because guanosine is methylated at the 7 position by a 7-methyl transferase. This cap acts to protect the mRNA from degradation and also is required during translation initiation in order to mediate a process known as ribosome recruitment. This process (ribosome recruitment) occurs through the association of the 43S preinitiation complex (composed of the small ribosomal subunit, eIF1, eIF1A, eIF2, eIF3 and eIF5 factors) with the 5' capped mRNA. After mRNA binding, the 43S preinitiation complex is ready to scan an initiation codon in order to start the translation.

Which is the most likely result if the Ubx gene was activated either before or after it normally is activated in the sequence of Hox gene expression?


A. The insect develops slightly shorter or longer abdominal legs.

B. The insect develops normal body parts at either a slower or more rapid rate.

C. The insect develops normal body parts but in an altered time sequence.

D. The insect develops legs in other parts of its body.

Answers

Answer:

D. The insect develops legs in other parts of its body.

Explanation:

HOX genes, also known as homeotic genes, are evolutionarily conserved genes (containing homeobox sequences) that encode master regulators of embryonic development in animals. Hox genes modulate the body plan of an embryo along the head-tail axis. In general, these genes are arranged in the same order as they are transcriptionally expressed along the anteroposterior body axis. Moreover, Ultrabithorax (Ubx) is a Hox gene that is responsible for the proper development of the third thoracic segment in insects. In Drosophila, it has been shown that different segments of the leg regulate their size in response to Ubx expression.

How does a fire help grasslands?

Choose all that apply

Answers

Answer:

In most grassland ecosystems, fire is the primary mode of decomposition

Explanation:

Grasslands burn more readily than forest and shrub ecosystems, with the fire moving through the stems and leaves of herbaceous plants and only lightly heating the underlying soil, even in cases of high intensity. In most grassland ecosystems, fire is the primary mode of decomposition, making it crucial in the recycling of nutrients. In some grassland systems, fire only became the primary mode of decomposition after the disappearance of large migratory herds of browsing or grazing megafauna driven by predator pressure. In the absence of functional communities of large migratory herds of herbivorous megafauna and attendant predators, overuse of fire to maintain grassland ecosystems may lead to excessive oxidation, loss of carbon, and desertification in susceptible climates. Some grassland ecosystems respond poorly to fire.

A fire helps grasslands through the following:

Keeps trees from overtaking the grasses.Preserve biodiversity.

Earth's core is the source of the energy that drives the movement of tectonic plates. Which two processes help transfer this energy outward to earth's crust?

Answers

Answer:The two processes are CONDUCTION and CONVECTION

Explanation:

The Energy produced in the Earth core is generated by  Sun, gravitational force , radioactive decay, and the  Earth' rotation, To maintain balance in the earth, The  processes of CONDUCTION and CONVECTION transfer energy (HEAT) to Earth's interior, which also helps the movement of  tectonic plates at a  constant rate.

Now, inside the earth mantle is made up of hot solid rock and because Conduction occurs more in solids, Its currents helps the continuous  transfer of heat energy  from the warmer mantle at  the bottom   to  the cooler  mantle  at the top While Convection currents in the core move thermal energy causing  the rising and sinking of warm and cooler molten rock inside Earth, thereby maintaining the motion of tectonic plates and  creating a balance in the earth.

Answer:

Conduction and Convection

Identify how information for specifying the traits of an organism is carried in the DNA.

Answers

Answer: DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).

Explanation:

The traits or characters are present in the DNA in the form of genes. Genes are short stretches of nucleotides present in DNA and represent the encoded message that is present in the individual.

What is a gene?

Genes are present in the DNA. It carries information about the traits that are expressed in an individual. Genes come from parents to offspring, so they are hereditary and pass from one generation to the next. From DNA, mRNA is formed from the gene by the process of transcription.

This mRNA is again converted to proteins or polypeptides by the process of translation. This product is the result of the message that is present in the gene. Example: melanin pigment and skin color variation. As different persons have variations in their genes, the production of this melanin protein synthesis varies, and as a result, skin color among individuals varies.

 

Hence, the information for specifying the traits is carried by genes present in DNA.

Compare primary succession and climax community. Be sure to identify how long-term survival of species is dependent on resources that may be limited.

Answers

Answer:

Primary succession is the colonization of species of organisms on life-less barren lands after a volcanic eruption, newly formed land, or sand dunes. Lichens and mosses are the known primary succession community of organisms that helps in developing conditions for secondary succession by breaking rocks and providing soil.

After a fair amount of time, there are new species of organisms that grow and colonize in the land and these are, and ultimately the community becomes fairly stable. A climax community is a more stable, mature community that undergoes little or no change which can live for hundreds of years on the land.

The long-term survival of species is dependent on various kind of resources that may be limited, this can be explained by the lichens and mosses that have enough amount of nutrition and resources during primary succession but as new organism comes with complex structure and competes with these lichens and mosses their number decline due to limited amount of resources.
