Answer:
Biological diversity - or biodiversity - is the term given to the variety of life on Earth and the natural patterns it forms. The biodiversity is the fruit of billions of years of evolution, shaped by natural processes and, increasingly, by the influence of humans.
Explanation:
Biodiversity is important to humans for many reasons. ... Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. If no changes are made in the ways humans use resources on earth, there will continue to be a degradation of biodiversity until human lives can no longer be sustained. Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to habitats for species.
Why is it difficult to fossilize large animals?
Answer:
The onerous elements of organisms, like bones, shells, and teeth have a far better likelihood of changing into fossils than do softer elements. One reason for this can be that scavengers typically don't eat these elements. onerous elements conjointly decay additional slowly than soft elements, giving longer for them to be buried.

Which phrase best defines evolution by natural selection? pls help
Answer:
A process of change in a species over time. Interbreeding among members of a population results in. No change in the relative frequencies of alleles in the gene pool.
Answer:
Process where certain individuals in a population survive because they are better adapted to their environment, so they are more likely to pass on their genes. The mechanism of evolution.

PLEASE HELP. I REALLY NEED THIS!!!!
Answer:
In nature, populations are usually evolving. The grass in an open meadow, the wolves in a forest, and even the bacteria in a person's body are all natural populations. And all of these populations are likely to be evolving for at least some of their genes. Evolution is happening right here, right now!
To be clear, that doesn't mean these populations are marching towards some final state of perfection. All evolution means is that a population is changing in its genetic makeup over generations. And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection. Other times, it comes from migration of new organisms into the population, or from random events—the evolutionary "luck of the draw."

If a flower is wilted, but not totally dead and withered yet, is the flower dead and it's dead flower body is in the process of decomposing, or is the flower like in the flower stage of being an old person, it lived and now it's old, but not dead yet?
Here's an example of the flower stage I mean. ^-^
Which of the following appear to cause movement of the Earth's tectonic
plates?

A male and a female, both with dimples, have a son without dimples. Which of Mendel's laws does this pattern of inheritance illustrate, and how do you know? AND What is the chance that a daughter of these parents would have dimples? Explain your answer.
Answer:
Explanation: Could you have drawn something different in question 3d? Explain. ... yes if both parents are heterozygous. 14 Chance no dimples. 1/4 dd 1/4 no ... If a woman is heterozygous for dimples and has 5 fingers, and a male is ... a Punnett square and calculate genotype and phenotype frequencies to explain your answer.
People also ask
According to the Mendel's Law of Segregation. Since, a male and a female, both with dimples, have a son without dimples which mean both the parents are heterozygous (Aa). since both are Aa × Aa there will be Aa, Aa, AA, aa. in which AA is dominant and aa is recessive thus the chance that a daughter of these parents would have dimple is 3/4.
What is Mendel's law of segregation?
Mendel's Law of Segregation states that a diploid organism passes a randomly selected allele for a trait to its offspring, such that the offspring receives one allele from each parent.
Thus, the chance that a daughter of these parents would have dimple is 3/4.

Describe the relationship between the respiratory and circulatory systems and ATP. Use the term reactants in your response.
Answer:
Cellular respiration, which generates ATP in your cells, requires oxygen to take place, also, it generates CO2 as a waste product. The respiratory system allows oxygen to diffuse into your blood, and carbon dioxide to diffuse out. The blood then carries the oxygen to the cells, so cellular respiration to continue. When the blood reaches the cells, it also takes the carbon dioxide out of the cells, and carries it to the lungs to get rid of it.

Answer: The Golgi apparatus modifies, packages, and sorts proteins for secretion or use within the cell
Explanation:
The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell. The Golgi apparatus is found close to the nucleus of the cell where it modifies proteins that have been delivered in transport vesicles from the RER.

2. In order to grow, animals with an exoskeleton must
a. Shed their skin
b. shed their shells
C. continue cell reproduction
d. find larger shells to inhabit.
a.shed their skin..
Explanation:
Exoskeleton
A true exoskeleton, like that found in arthropods, must be shed (moulted) when it is outgrown. ... The new exoskeleton is still capable of growing to some degree, however. Animals of the order arthropoda, like lizards, amphibians, and many other animals that shed their skin, are indeterminate growers

During meiosis, a process known as crossing over occurs. Which statement below summarizes the results of crossing over?
O Homologous chromosomes make copies of each other.
Genetic information is removed from both chromosomes.
O DNA winds up into chromosomes and genetic information is deleted.
O DNA is exchanged between homologous chromosomes, resulting in genetic variation.
Answer:the answers is B
Explanation:
Because reproduction occurs between homologous a chromosome
During meiosis, a process known as crossing over occurs. Genetic information is removed from both chromosomes.
What is meiosis ?Meiosis is the process where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.
Humans have 46 chromosomes in every cell, where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.
Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.
Secondly Prometaphase I where Spindle fibres attach to the centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.
Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

2. Give a reason why earth worms come out of the soil when it has rained.
for wallowing it?
Explanation:
Oxygen diffuses easily through air, and the soil stays aerobic because oxygen comes in from the surface. But after a rain, the soil pores and the worm burrows fill with water. The worms can't get enough oxygen when the soil is flooded, so they come to the surface to breathe.

Answer:
How is the endocrine system related to the nervous system in terms of its regulatory activity?
For one, the endocrine system uses chemical signaling (hormones, produced by glands) while the nervous system uses electrical signaling (neural impulses). The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are more short-lived.
