proved that dna Carries genetic information
Answer:
Hope it helps...
Explanation:
The Hershey–Chase experiments were a series of experiments conducted in 1952 by Alfred Hershey and Martha Chase that helped to confirm that DNA is genetic material. Hershey and Chase and subsequent discoveries all served to prove that DNA is the hereditary material.
Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. In eucaryotes, DNA is contained in the cell nucleus.

A shipwrecked sailor is stranded on a small desert with not fresh water to drink. He knows he could last without food up to a month, but if he didnt have water to drink he would be dead within a week. Hoping to postpone the inevitable, his thirst drove him to drink the salty seawater. He was dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all?
Answer: The salt dried and dehydrated him even further.
Explanation: When we become dehydrated, the sodium concentration in the body is already elevated. Adding salt only aggravates the condition by forcing the kidneys to excrete more water in order to eliminate the extra salt.
HELP YALL I NEED IT QUICKKKKK Hybrid seeds are deliberately crossbred for particular traits, such as growth pattern or disease resistance. They have been hand-pollinated and are patented, often sterile, and genetically identical within food types. These plants are usually grown in a monocultural environment and are cultivated for mass production and sale. They must be sturdy to withstand mechanical picking and cross-country shipping. They do not compare to the quality and taste of heirloom plants, but they do produce large, healthy fruit that appeals to most shoppers. Unlike heirloom seeds, if one saves a hybrid seed, one will not get the same plant again.

Select an ecosystem that is familiar to you and describe the biotic and abiotic factors that exist there?
Answer:
Forest Ecosystem
An ecosystem is composed of two main components: biotic and abiotic factors. Biotic factors are the living parts of the ecosystem, such as plants, animals, insects, fungi, and bacteria. Abiotic factors are the non-living parts of the ecosystem, which influence the size and composition of the living parts: these are components like minerals, light, heat, rocks, and water.
Biotic Factors by Type
The most obvious features of any forest ecosystem are its trees, the dominant biotic feature. They dominate the ecosystem: both in terms of visibility and in terms of biomass. However, they are only one type of organism living in a forest. Other biotic factors include:
shrubs , flowering plants , ferns , mosses , lichens , fungi , mammals , birds , reptiles , insects , worms , microbes
Abiotic Factors by Type
The most important abiotic feature of a forest ecosystem may not be obvious, despite its ubiquity and importance: sunlight. Tangible abiotic factors include soil, minerals, rocks, and water. But abiotic factors can be intangible, such as temperature, other types of radiation, and the chemistry of soil and water.
Biotic Factors by Function
Ecologists frequently group an ecosystem's factors by what role they play in the system, rather than by what particular species they are. This is known as a functional classification.
These functions relate to the movement of energy through an ecosystem, and trees — along with other photosynthetic plants — are the chief primary producers. This means that trees convert the sun's energy into food energy, which is then used by other members of the ecosystem.
These other members of the ecosystem can also be categorized. Primary consumers are, for example, herbivores that eat the primary producers. Secondary consumers are the carnivores and omnivores that eat the primary producers. Decomposers are the scavengers, microbes, and fungi that consume the droppings and the carcasses of other organisms.
Abiotic Factors by Function
The abiotic factors of a forest fall less obviously into functional classifications, but keep in mind that the energy transferred among the various biotic categories is itself a foundational abiotic element. This energy occurs in the form of solar radiation, which includes both visible light and heat (infrared).
Primary producers (plants like trees and shrubs) convert the light into carbohydrates, a form of energy that can be consumed by other organisms. The function of other abiotic factors relies on the minerals they contain, such as the nitrogen in the soil or the hydrogen in water molecules.
An ecosystem consist of various biotic and abiotic factors which interact with each other. A grassland ecosystem is a terrestrial ecosystem which have grass as the main producers (dominant) living thing.
What is a Grassland Ecosystem?
A grassland ecosystem is a type of terrestrial ecosystem in which grasses and the herbaceous plants are the dominant species. Grass controls the grassland ecosystems as they are the main producers of the ecosystem with few or no trees where there is not favorable conditions for a forest. It is more like a dry and desert ecosystem. Therefore, it is also called as a transitional landscape.
The four important abiotic components of grassland ecosystem includes climate, parent material and soil, topography, and natural disturbances. Climate includes the rainfall pattern, temperature and wind patterns of a particular area.
Biotic Factors in the Grassland ecosystem include Plants, Insects (Invertebrates), Grazers, and Predators.

In your letter, you need to explain how the theory of evolution is supported by evidence. Be sure to include the 4 pieces of evidence for evolution as well as an example of each.
The evidence of evolution was posited by Charles Darwin. The theory of evolution states that all species are related and that they change over time
The different postulates of Drawin support the natural selection phenomenon. Darwin stated that the organisms that are fit and are able to change according to evolution are able to survive. This was known as the survival of the fittest.
The evidence of the evolution can be studied by fossil record , comparative embryology , molecular biology , and comparative anatomy.

1. Sodium is a silvery solid that reacts violently with water and chlorine. When they
combine to form the compound sodium chloride known as salt, there is a
fundamental change in the properties. Salt is often added to our food when
cooking and it is safe to eat. Which of the following statements supports the idea
presented?
Answer: Options are not given, here are the options.
. True to all compounds, they no longer have the properties of the elements
that makes them up.
B. True to some compounds, it maintains the properties of the elements that
makes them up.
C. True in all elements, it maintains its properties even after it combines with
other elements.
D. True to all elements, they have the properties after they are combined.
The correct option is D.
True to all elements, they have the properties after they are combined.
Explanation:
Elements are pure substances which can not be divide by any form of chemical means.
True to all elements, they have the properties after they are ccombine because elements contain atoms and atoms is the smallest indivisible units which retain chemical properties because chemical bonds are formed between the atoms of elements.

Compare the circulatory system of a plant and animal.
Answer:
vascular plants have a top and bottom ,a trunk and branches ,leaves or needles the bottom is a system of roots. Xylem and phloem make up transportation system of vascular plants. Xylem is made of vessels that are connected end to end to move water around.
Open and closed circulatory systems are found in animals. blood vessels transport all guilds into a cavity. when the animal moves the blood inside the cavity moves around the body in all directions. most invertebrates like crabs, insects, snails etc...have an open circulatory system.

A company wants to build a new store. After reviewing the piece of land it is determined that a threatened woodpecker nests in that area .If the company is granted permission to build , what is the most environmentally responsible action by the company
Answer:
Explanation:
If the piece of land is forested or covered with many trees, the company can decide not to bring down all the trees (leaving some trees standing) and move as many as possible nests to the available trees within it's land. This will prevent emigration of the woodpeckers and can ultimately help conserve the woodpeckers in that land and indeed the area in which the land is situated.
This is most environmentally friendly because killing or scaring away of the birds by destroying there homes could lead to imbalance in the environment and even cause gradual extinction of the birds in the environment/area.
Which of the following represents a possible chromosome number of a species that uses sexual reproduction, and why?
A
62, because this number will create a diploid cell, the result of both female and male gametes combined.
B

С
23, because this number will create a diploid cell, the result of both female and male gametes combined.
o
D
23, because this number will create a haploid cell, allowing both female and male gametes to be combined
Answer:
B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.
Explanation:
Sexual reproduction involves two organisms to come together (male and female). Sexually-reproducing organisms make use of a process called MEIOSIS to produce gametes or sex cells, which have a reduced number of chromosomes as the parent cells producing them.
A sexually reproducing organism must contain a complete diploid chromosome number (2n) that allows it to produce cells with a haploid chromosome number via meiosis. The haploid gamete cells that result from each meiotic divisions of male and female parents can combine to form a whole diploid organism.
The number of a species should be uses se-xual reproduction,
B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.
Se-xual reproduction:It includes the two organisms for come together i.e. male and female. It make use of a process known as MEIOSIS to generate gametes. A se-xually reproducing organism should contain a complete diploid chromosome number (2n) that permits it to generate cells with a haploid chromosome number via meiosis.

According to natural selection theory, Different species occupying the same habitat will adapt to that habitat by undergoing the same genetic changes Adaptations beneficial at one time should generally be beneficial during all other times Well-adapted individuals have more offspring, and thus contribute more to the next generation's gene pool, than do poorly adapted individuals. Adaptations beneficial in one habitat should generally be beneficial in all other habitats
Answer:
The most correct statement is - Well-adapted individuals leave more offspring, and thus contribute more to the gene pool, than poorly adapted individuals.
Explanation:
Adaption in natural selection is a species, time-specific, and habitat-specific process. So, it means if a species is adapted to genetic changes in a particular habitat, it is not necessary that all other species also adapt to similar genetic changes.
Similarly, if a species has beneficial adaption for a particular habitat, it is not necessary it will be beneficial for the other habitat as well.
Thus, natural selection leads to the well-adapted individual that leave more offspring and contribute more to the gene pool.
