What wave lengths of light do each of the pigments reflect?
Answer:
All photosynthetic organisms have chlorophyll which absorbs violet–blue and reddish orange–red wave lengths chlorophyll reflects a green and yellow–green wavelengths accessory photosynthetic pigments by including chlorophyll beta–caeotene that absorbs energy therefore then the chlorophyll does not absorbs. Most pigments work by absorbing certain wavelengths of lights the other wavelengths are reflected or scattered that which causes you to see those colours the nergy of the light is absorbed to excite the electrons so it no longer able to seen by your eyes

As predicted by the Punnett
square, (blank)
% of the
offspring have black fur for this
cross.
Answer:
Guy on top is correct. It is 100%
Explanation:
As predicted by the Punnett square, 100% of the offspring have black fur for this cross.
When two individuals with the genotype BB (homozygous dominant for black fur color) are crossed, their Punnett square will look like:
| B | B
--|----|----
B | BB | BB
--|----|----
B | BB | BB
All the offspring will have the genotype BB, which means they will be homozygous dominant for black fur color. Therefore, all the offspring will have black fur.

How does a mouse obtain energy for everyday functions? How might this look different compared to how an own obtains energy?
Answer:
A mouse would obtain energy from plants that have vitamins and minerals, and protein from things like nuts. An owl would get protein from eating a mouse and vitamins and minerals from the things the mouse ate.
Explanation:
It's all one big circle. These nutrients would provide the energy needed to perform everyday tasks.
What do all members of the swine species always have in common? They always have the same number and kinds of chromosomes. They are always preyed upon by the same predators. They always occupy the same habitat at the same time. They always occupy the same position in the food web no matter where they live.
Answer:
Members of the swine species always have the same number and kinds of chromosomes
Explanation:
The swine species always have their food habits in common. They are omnivorous and they also due to ancestry have the typical type of genes and chromosomes inscribed in it. Hence swine are used in research industry nowadays like dogs and monkeys.
Wild boars, hogs and pigs all have just small differences externally. Their anatomy and physiology are identical. They are all mammals. They are highly intelligent and talented ones. They have their physiology identical to ours which helps in research scientist to experiment and finds cure for human.
Answer:
biological definition of species, which works for sexually reproducing organisms, is a group of actual or potential interbreeding individuals. There are exceptions to this rule. Many species are similar enough that hybrid offspring are possible and may often occur in nature, but for the majority of species this rule generally holds. The presence in nature of hybrids between similar species suggests that they may have descended from a single interbreeding species, and the speciation process may not yet be completed.
Given the extraordinary diversity of life on the planet there must be mechanisms for speciation: the formation of two species from one original species. Darwin envisioned this process as a branching event and diagrammed the process in the only illustration found in On the Origin of Species (Figure 1a). Compare this illustration to the diagram of elephant evolution (Figure 1b), which shows that as one species changes over time, it branches to form more than one new species, repeatedly, as long as the population survives or until the organism becomes extinct.
Explanation:
For speciation to occur, two new populations must be formed from one original population and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed. Biologists have proposed mechanisms by which this could occur that fall into two broad categories. Allopatric speciation (allo– = “other”; –patric = “homeland”) involves geographic separation of populations from a parent species and subsequent evolution. Sympatric speciation (sym– = “same”; –patric = “homeland”) involves speciation occurring within a parent species remaining in one location.
Biologists think of speciation events as the splitting of one ancestral species into two descendant species. There is no reason why more than two species might not form at one time except that it is less likely and we can conceptualize multiple events as single splits occurring close in time.
Allopatric Speciation
A geographically continuous population has a gene pool that is relatively homogeneous. Gene flow, the movement of alleles across a species’ range, is relatively free because individuals can move and then mate with individuals in their new location. Thus, an allele’s frequency at one end of a distribution will be similar to the allele’s frequency at the other end. When populations become geographically discontinuous, it prevents alleles’ free-flow. When that separation lasts for a period of time, the two populations are able to evolve along different trajectories. Thus, their allele frequencies at numerous genetic loci gradually become increasingly different as new alleles independently arise by mutation in each population. Typically, environmental conditions, such as climate, resources, predators, and competitors for the two populations will differ causing natural selection to favor divergent adaptations in each group.

fossils are taken as the strongest evidence so far regarding the evolution of organisms. justify this statement
Answer:
No present empirical evidence supports the idea of that natural causes can result in an increase of complexity. The idea that descent with modification has happened in the past is supported by the fossil record. This makes the fossil record the strongest evidence for Darwin's theory of evolution
Explanation:
Fossils are defined as the preserved remains or traces of animals, plants, and other organisms from the past that are important evidence for evolution because they show that life on Earth was different from what was once found on Earth.
What are Fossils?A fossil is defined as the preserved remains, impression, or trace of a once-living thing from a past geological age, including bones, shells, exoskeletons, fossilized traces of animals or microbes, amber, hair, petrified wood, and DNA.
The totality of fossils is known as the fossil record. These are the preserved remains of plants and animals whose bodies were buried in sediments such as sand and mud at the bottom of ancient seas, lakes and rivers, including any preserved traces of life which are usually over 10 000 years old.
The different types of fossils include:
1. Petrified fossils
2. Mold and cast fossils
3. Carbon film fossils
4. Trace fossils
5. Reserved remains, etc.
Thus, Fossils are defined as the preserved remains or traces of animals, plants, and other organisms from the past that are important evidence for evolution because they show that life on Earth was different from what was once found on Earth.

A population of birds lives on a small island. Another population of the same species lives on the mainland. The distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of sandbars and tiny islands have formed between the island and the mainland. What is the most likely effect of this?
Answer: An increase in gene flow between the bird populations.
Explanation:
The population of bird species living in the island and other one in mainland are geographically isolated because of the distance between the island and the mainland is large that does not allow birds to fly and cover the entire distance. This is the reason of reproductive isolation and restricts the gene flow between the two populations. But the creation of sandbars and tiny islands between the island and mainland created a way so that island and mainland birds can meet and reproduce. This will allow the increase in the gene flow between the two separated population of bird species.

what are the types of gametes
In certain organisms, like humans, there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile. The haploid condition of the two gametes is essential so that at fertilization during sexual reproduction the integrity of the chromosomal number is maintained throughout generations.
Hope this helps.
Answer:
Examples of Gametes. The two most common gametes are sperm and ova. These two haploid cells can undergo internal or external fertilization and can differ from each other in size, form, and function. Some species produce both sperm and ova within the same organism
