What do you mean by Shadow?Shadow may be defined as the dark figure thrown upon a surface by a body blocking the rays from a source of light.
When the sun is at an angle usually in the early morning or late afternoon, the shadow of any object is found to be larger as compared to its original shape.
Therefore, the length of the shadow on the sun stick differs at noon and in the late afternoon, the shadow is longer in the late afternoon because the sun is at an angle.

Why is a plant classified as an autotroph
Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

why is heating water changing its volume
Answer:
As heat increases water begins to evaporate. Evaporation begins at 0C and is at full effect at 100C. So by increasing heat you are increasing rate of evaporation and thus more and more water molecules are lost to the gas phase reducing volume of the water.

After you set up a fish tank, you are sure to see algae growing in it. There is plenty of light, fertilizer in the form of fish droppings, and plants or glass for algae to cling to. You may see green strings of algae in the water or green spots growing on the glass. Your whole aquarium can turn green if you don’t stop the algae. To prevent the problem, you can add algae-eating fish or microorganisms to the water. Covering the aquarium for a few days will also kill algae, which need photosynthesis to survive.

Homologous chromosomes may exchange segments; this is called crossing over. crossing over increases genetic variability. when does crossing over occur?
A trade of chromosome segments among non-sister homologous chromatids happens and is referred to as crossing over.
Crossover happens while chromosomes, usually homologous times of the equal chromosome, spoil after which reconnect however to the specific quit piece. If they spoil on the equal location or locus withinside the collection of base pairs, the end result is an trade of genes, referred to as genetic recombination.
What are homologous chromosome?Homologous chromosomes are made from chromosome pairs of about the equal length, centromere position, and marking pattern, for genes with the equal corresponding loci.

Which events caused the oceans to form? select two options. the sun released a strong burst of water vapor. as the earth cooled, water condensed. materials collided due to strong gravitational forces. the ozone layer formed to protect against harmful uv ray exposure. water vapor increased during formation of the early atmosphere.
The events that caused the oceans to form are as the earth cooled, water condensed and the sun released a strong burst of water vapor.
How oceans are formed?Oceans are formed millions of years ago when the water drained into the great hollows on the Earth's surface, the primeval ocean came into existence.
These two events are responsible for the formation of the oceans which is the primitive habitat of the aquatic ecosystem.

Nathan is comparing the cells from a species of amoeba with a species of bacteria. Both species are unicellular, meaning individuals exist as a single cell. Which characteristic of the cells should Nathan expect to be the same in both species?
A. The size and shape of the cell
B. The method of reproduction, or making more cells of the species
C. The organization of DNA into structures such as chromosomes and the cell nucleus.
D. The genetic code that has used by DNA and RNA to direct protein synthesis
Given what we know, we can confirm that Nathan can expect the means of reproduction to be the same in both species, meaning that the correct answer would be option B.
Why is option B the correct choice?When dealing with unicellular organisms, many aspects will always remain the same between the distinct species. One such aspect is the reproduction method used universally by all unicellular species, that being reproduction through binary fission. The organism replicates its DNA and then divides into two identical cells.
Therefore, we can confirm that Nathan can expect the means of reproduction to be the same in both species, meaning that the correct answer would be option B.

The pedigree is not found here, but it is possible to track the inheritance of an autosomal/X linked trait by observing its presence in the family tree.
What is a pedigree?A pedigree is a genealogical tree used to track the inheritance pattern of a given trait in a family tree, which can be dominant or recessive.
An autosomal dominant trait is inherited in a dominant fashion and it is located on a pair of homo-logous autosomal chromosomes.
An X-linked trait is inherited on chromosome X and these traits show differential inheritance because males inherit only one X chromosome.

compare the effect of the ozone in the troposphere with its effect in the stratosphere where is it harmful where is it helpful
Answer:
Ozone in the stratosphere is helpful; it absorbs harmful UV-B and UV-C waves from the sun, which are both known to cause sunburn and skin cancer. On the other hand, ozone in the troposphere is very damaging; it is a major component of photochemical smog, and it causes eye, nose, and lung irritation and aggravates asthma.

Even-aged management practices involves clearing trees that
are all the same height
b. are all the same weight
C. are all near the same age
d. are all of widely different ages
Please select the best answer from the choices provided
Answer: C. Are all near same age.
Explanation: Even-aged firewood management practices refer to the practice of clearing of trees that "are all near the same age"as this technique is usually adopted to maintain the proportion and continuity of various species of trees(thus, cutting of the trees of same age). This practice is employed to minimize the costs and attain a coeval and comrade group of trees. It proves quite beneficial in reestablishing the succession of a native breed. It involves the selection of trees at first depending on the size, desirable species, etc. followed by clearcutting of unmerchantable(undesired) trees. This technique is usually adopted to maintain the proportion and continuity of various species of trees.
