Answer:
- Most animals have the capacity for active movement
- Animal zygotes undergo mitotic divisions called cleavage
- All animals are heterotrophs
Explanation:
Animals, also known as metazoans, are multicellular eukaryotic organisms from the kingdom Animalia. Animals are a monophyletic group, i.e., all animals are derived from a common ancestor. Animals can be classified into two main groups: 1- invertebrates that don't have a backbone inside their body (e.g., earthworms, octopus, snails, insects, etc) and 2-vertebrates that have a backbone inside their body (e.g., fish, amphibians, reptiles, birds, mammals). Cleavage refers to the division of animal cells in the early embryo. In animals, the zygotic cell divides by mitosis (i.e., cleavage), into smaller cells called blastomeres. Some of the most common characteristics of the animal kingdom are:
- heterotrophy: animals cannot produce their own food and obtain energy by feeding organic material present in other organisms
- generally reproduce through sexual reproduction
- animal's cells do not have cell walls
- they are able to move in almost one stage of their lives
- they can respond to external stimuli by nerve cells and/or muscle cells

Which is NOT a benefit of xenophyophores in a habitat?
1 They maintain benthic biodiversity.
2 They increase populations of isopods, mollusks, and crustaceans.
3 They churn up sediments that build up on the ocean floor.
4 They convert salt and iron into energy and nutrients.
The correct answer is 4. They convert salt and iron into energy and nutrients.
Explanation
Xenophiophores are large single-celled organisms generally found deep in the deep sea. They are characterized by being very delicate organisms, which makes it difficult for scientists who intend to study them since they are easily damaged by manipulation. However, in the studies that have been carried out on these organisms, it has been found that they are irreplaceable agents in the sediment deposition process and the maintenance of the biological diversity of benthic organisms. Also, it has been shown that in the areas where these organisms are found there are three to four times more benthic crustaceans, echinoderms, and mollusks than the equivalent areas not inhabited by these organisms. On the other hand, none of these studies has proven that They convert salt and iron into energy and nutrients. Therefore, the correct answer is 4. They convert salt and iron into energy and nutrients.

A young man claiming to be the son of Howard Hughes is suing the estate for his inheritance. Hughes (multimillionaire, inventor, businessman, and subject of the 2004 film, Aviator), did not leave behind any heirs upon his death. The judge overseeing this case, orders blood tests. Howard Hughes has blood type AB, the mother of the young man has type A blood, and the young man had type O. If you were the judge in this case, what would be your ruling?
Answer:
The young man is not the son of Howard Hughes.
Explanation:
The human blood system works on codominance type of inheritance in the case of blood group A and blood group B present together however, in blood group O it still follows the law of dominance as antigen O is recessive in present of any other antigen.
We know Howard Hughes had blood type AB
So, the genotype would be - IAIB
We also know that the mother of the young man claiming has a blood type A
So, possible genotypes would be - IAIA (case 1) or IAi (case 2)
For case 1,
The possible genotypes for the man claiming would be
IAIB X IAIA --------> IA IA, and IAIB.
According to case 1, he is not the son of Howard.
For case 2,
The possible genotypes for the man claiming would be
IAIB. X I A i ---------> IA IA , IAIB I A i and IB i
Both cases show that the man claiming is not the son of Howard as the blood group of the man is O and the genotype should be ii.

Explain the importance of using engine powered pump for irrigation works.
Answer and Explanation:
Engine irrigation pumps are used to propel water into the irrigation channels, providing full water supply to agricultural crops. The use of the engine pump has advantages and disadvantages. Among the advantages, we can present the simplicity of operation of these pumps, being easily operated efficiently. They also save energy and are essential for irrigation with more viscous liquids, when necessary. This feature is the main reason for using this type of pump.
Among the disadvantages we can say that these pumps have a slower and less accurate work.
Describe the differences between the forces of magnetism and gravity.

Gravity is not the same thing as magnetism. They are in fact entirely distinct forces. Gravity is a force that works with weight between two objects. Magnetism can pull or separate the two objects, depending on how the magnets point.
Explanation:
after mitosis what percentage of the original cell's genetic information can now be found in each daughter cell?
•100%
•25%
•50%
•75%
Answer:
•100%
Explanation:
Mitosis is a type of cell division which results in two daughter cells that are genetically identical to the original or parent cell. The identical nature of the daughter cells to the parent cell means that the number/amount of genetic material is maintained in the cells i.e. a diploid (2n) cell with 10 chromosomes will undergo mitosis to produce two diploid (2n) daughter cells with 10 chromosomes each.
Based on the explanation above, at the end of mitosis, 100% of the original cell's genetic information (DNA) can now be found in each daughter cell. Note that, this is contrary in meiosis, which reduces the genetic content by half.

Explanation:
write a paragraph that explains what the causes of Long term climate cycles are. Give examples
Explanation:
Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.
Below are some of the regional impacts of global change forecast by the Intergovernmental Panel on Climate Change:
North America: Decreasing snowpack in the western mountains; 5-20 percent increase in yields of rain-fed agriculture in some regions; increased frequency, intensity and duration of heat waves in cities that currently experience them.
Latin America: Gradual replacement of tropical forest by savannah in eastern Amazonia; risk of significant biodiversity loss through species extinction in many tropical areas; significant changes in water availability for human consumption, agriculture and energy generation.
Europe: Increased risk of inland flash floods; more frequent coastal flooding and increased erosion from storms and sea level rise; glacial retreat in mountainous areas; reduced snow cover and winter tourism; extensive species losses; reductions of crop productivity in southern Europe.
Africa: By 2020, between 75 and 250 million people are projected to be exposed to increased water stress; yields from rain-fed agriculture could be reduced by up to 50 percent in some regions by 2020; agricultural production, including access to food, may be severely compromised.
Asia: Freshwater availability projected to decrease in Central, South, East and Southeast Asia by the 2050s; coastal areas will be at risk due to increased flooding; death rate from disease associated with floods and droughts expected to rise in some regions
Which of the following factors decrease biodiversity? (Choose all that apply)
a. habitat destruction
b. unpredictable precipitation
c. warm temperatures
d. freezing temperatures
Answer:
habitat destruction, unpredictable precipitation, and freeing temperatures.
Explanation:
i took the quiz
The destruction of the habitat, unpredictable precipitation, and freezing temperatures decreases biodiversity. Thus, options a, b, and d are correct.
What is biodiversity?Biodiversity is the variety of life that sustains on earth and lives in a particular habitat. The biodiversity can be measured based on the ecosystem, species, and genetics. It comprises the ecological and evolutionary process.
The destruction of the habitat of a species can lead to a decrease in biodiversity as it affects the ecosystem and the ecological pyramid as a whole and will affect the population of the species.
The unpredictable precipitation can affect the species and the habitat as it may lead to floods that will destroy the habitat hence resulting in the loss of species.
Similarly, the decrease in temperature will affect many species as they will not be able to cope with low temperature resulting in their death.
Therefore, the unpredictable precipitation, freezing temperature, and destruction of habitat lead to a decrease in biodiversity.

A mountain range divides a freshwater snail species into two large isolated populations. Erosion eventually lowers the range and brings the two populations together again, but when they mate, the resulting hybrids all produce sterile young. This scenario is an example of:
Answer:
allopatric speciation.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction.
II. Asexual reproduction.
In this scenario, a freshwater snail species is divided into two (2) large isolated populations by a mountain range. This range is then lowered by an erosion and as such bringing the two populations of the freshwater snail species together again.
However, when the two snail species mate, the resulting hybrids all produce sterile young snails. Thus, this scenario is an example of allopatric speciation.
Allopatric speciation is also referred to as geographical speciation and it can be defined as a process in which two (2) biological populations of the same species become isolated from each other by geographical barriers or changes such as mountain range, emigration, etc. Thus, allopatric speciation is dominant with living organisms that reproduces sexually and it causes the isolated species to evolve newly with distinctive traits.
What functions does the red blood cell do for a human?
Answer: Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled. The function of the red cell and its hemoglobin is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it is excreted.

Answer: Derek is TT and his wife Ashley tt. Thus children are Tt
Explanation: T Is dominant and t is recessive.
Derek can curl his tongue but his wife, Ashley, cannot. All nine of their children can curl their tongues. Because, the trait of Derek is TT and the trait of his wife Ashley tt.
Thus, the trait of children are Tt
Why Derek cannot curl his tongue?
The tongue rolling ability occurs due to the influence of a dominant allele of the gene. A person who has either one or two copies of the dominant allele will be able to twist their tongue. In the case that a person is born with two recessive alleles, they cannot twist their tongue.
