What are two different ways that
weathering can happen?
Chemically & Physically(mechanically)
erosion & physically (mechanically)
chemically & deposition
Answer:
Chemically & Physically(mechanically)
Explanation:
Weathering is the wearing away of rock found at the surface of the earth. There are different ways weathering can occur and they include;
1. Mechanical weathering: This is the breakdown of rock into bits or fragments. Physical factors such as water can lead to this breakdown. When water falls into the pores and cracks of rocks, pressure can be created that will eventually result in the breakdown of these rocks.
2. Chemical weathering: This type of weathering causes a change in the physical makeup of the rock. The new form of rock created is more prone to erosion. Temperature is factor that can speed up chemical weathering.

Cells of the skeletal system are specialized in their structure to store minerals. Which of the following is the function of these cells?
Produce chemicals that transmit signals.
Prevent the spread of disease in the organism.
Provide support to the body.
Absorb excess water released by digestion.
Answer: Provide support to the body.
Explanation:
The skeletal system is a system which is formed by the bones. The bones are important for the structure and function of the body. The bones are connected with the muscles to allow the movement of the body, and they protect the vital organs like heart, lungs, brains, and others. They provide support to the soft tissues, organs, and muscles of the body. They keep the human body upright. The skeletal system provide shape to the body. It provides support by acting as regions of attachment of soft body parts and muscles.
Name and give examples of 2 major types of mutations. What do they have in common? How are they different?
Answer:
The correct answer would be - Two major types of mutations are deletions and substitutions.
Explanation:
The two major types of mutations are deletion and substitution, other than these there are many more mutations that are categorized under gene mutations and chromosomal mutation.
The deletion mutation takes place in the conditions where the DNA deletes or missed copying the nucleotide in a new DNA molecule. This type of mutation can occur in one or more nucleotides. Whereas Substitution mutation occurs when there is a wrong nucleotide added to the DNA sequence or substitute with other.
Both could be deleterious and takes place at the nucleotide level. Both mutation depends on the number of nucleotide or the location of the mutation on the gene.
Question 1. What change led to an increase in the number of light-colored moths within the population?
1. More mutations
2. Decreased pollution
3. More dark colored trees
4. Fewer humans
Question 2. Claim: Individuals in a population have genetic variations that can be passed on to their offspring. Refer back to the rabbits in the desert from the natural selection activity we did in class. How could an organism's traits influence the survival rate of the population?
Answer: 1. 1. More mutations. 2. According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Explanation:
The real length of one villus is 0.8 mm
Calculate the image length if the villus is viewed at a magnification of x20
magnification = size of image / size of real object
Answer:
Explanation:
Re arrange formula=Size of image=Magnification*size of real image
0.8mm*20=16mm
The image length will be "16 mm". A further explanation is below.
Given:
Magnification,
20Size of real image,
0.8 mmAs we know the formula,

3) identify and describe three abiotic characteristics of ecosystems. Give an example of how each
characteristic could be affected by a human activity
Answer:
The abiotic characteristics of an ecosystem that affects man includes: Land surface, rainfall and relative humidity.
Explanation:
In the ecosystem, man occupies the terrestrial habitat which is affected by the abiotic factors listed above.
Abiotic (non- living) factors determine the type of biotic (living) community that is found in an ecosystem. These factors include Land surface, rainfall and relative humidity, just to mention a few.
--> LAND SURFACE: This is responsible for the marked variation in the vegetation of a place. For example, a mountain in the tropics may have a rain forest vegetation at it's base and an afroalpine vegetation near its peak. The gradient of the slope affects the growth of organisms. A steep slope encourage fast run - off of water and therefore encourages erosion, which results in shallow and infertile soil. This in turn AFFECT man's farming activities as there would be little to no crop yield.
--> RAINFALL: Water is a very important abiotic factor that affects life. The main source of water to terrestrial habitat is rainfall. When rain falls, a greater percentage of it sinks into the soil while the rest run- off into water bodies. Water is absorbed by root hairs into the plant and used for photosynthesis to produce food. The absence of rainfall in the environment of man could lead to drought which AFFECTS man negatively.
--> RELATIVE HUMIDITY: This is a measure of the amount of moisture in the atmosphere. It's usually high in hot wet regions. It affects the rate at which water evaporates from the body surfaces of organisms. Low relative humidity cause more water (sweat) to evaporate from body surfaces giving the human body a cooling effect. But in high relative humidity, the sweat cannot evaporate leaving the body feeling hot and sticky. This AFFECTS man as the body tries to cool off in a harder way by increasing rate of respiration and depth of blood circulation.

have a nice day!;)
The probable genotypic ratio of their children is 50% Hh : 50% hh because the man is heterozygous for the hitchhiker’s thumb, hence option A is correct.
What is a heterozygous condition?In some crosses, there are two conditions, in which some alleles are heterozygous and some are homozygous. In the homozygous trait, both alleles are the same, it may be dominant or recessive HH and hh, respectively.
The cross is between a woman who does not have a hitchhiker’s thumb and a man who is heterozygous for a hitchhiker’s thumb.
Cross: Hh X hh
Gametes: H and h
Genotype: Hh, Hh, hh, hh
Phenotype: 50% of hitchhiker’s thumb and 50% not having hitchhiker’s thumb.
The cross is attached in the image below.

Graded for correctness: In humans, the ability to digest lactose beyond childhood is determined by a single gene on chromosome 1. L denotes the allele that gives the ability to digest lactose and l denotes the inability to digest lactose. On chromosome 3 is the gene for widows peak. A denotes the allele for no widows peak and a denotes a widows peak. A woman volunteers to be a participant in a genetic research study. Her genotype is LlAa. A doctor harvests a single egg from her body. The genotype of her egg is LA. How did her chromosomes line up at the metaphase plate during meiosis
Answer:
Metaphase I:
Homologous chromosomes are placed in the equatorial planeChromosomes carrying the dominant alleles, L and A, face one of the polesThe homologous chromosomes, carrying the recessive alleles, l and a, face the opposite pole.Metaphase II:
Chromosomes carrying the dominant alleles, L and A, are placed in the equatorial planeOne of the chromatid sisters of each chromosome faces one of the polesThe other chromatid sisters of each chromosome face the opposite pole.You will find the image in the attached files.
Explanation:
During metaphase I, homologous pairs migrate to the equatorial plane. They randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
During metaphase II, fibers of the spindle apparatus take chromosomes toward the equatorial cell plane, where they line up. Sister chromatids are holden together until they reach the Anaphase, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again. Finally, cytokinesis occurs.
In this example, we will assume no crossing-over in the prophase. I will propose the two metaphase stages.
Metaphase I: Pole 1
Chromosome 1 ---------L---- -----------A--------- Chromosome 3
----------L---- -----------A---------
Equatorial plane.....................................................................................................
Chromosome 1 ---------l---- -----------a--------- Chromosome 3
---------l---- -----------a---------
Pole 2
In this scheme of Metaphase I, homologous chromosomes are already aligned in the equatorial plane. Each homologous chromosome is facing a pole. So, in the superior part of the scheme, we have chromosomes 1 and 2 carrying the dominant alleles L and A. Both chromosomes are facing pole 1. Then, we can recognize the equatorial plane, and on the other side, we find the homologous chromosomes 1 and 2, facing pole 2, and carrying the recessive alleles, l and a.
During anaphase I, homologous chromosomes will separate and migrate to different poles. In this example, we are interested in chromosomes carrying the dominant alleles that migrate to pole 1. LL and AA.
Metaphase II: Pole 1
Chromatid 1 ---------L---- -----------A-------- Chromatid 3
Equatorial plane.....................................................................................................
Chromatid 1 ----------L---- -----------A--------- Chromatid 3
Pole 2
During metaphase II, each chromatid sister carrying the dominant alleles faces a different pole. During anaphase II they separate and migrate again.
The total result of meiosis in this particular cell is the formation of 4 haploid cells -gametes-: LA, LA, la, la

1) Read the following paragraph and answer the following questions.
The countries which do not have oil reservoirs in their land, import oil from other countries. But sometimes during transportation of oil through sea routes, accidental oil spill occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removal of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp and Alcanivorax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction of carbons with oxygen resulting in formation of CO2 and water. Like oil spills cause damage
to aquatic life, plastic forms the major part of the garbage on the land. Plastics are difficult to degrade as they are made up of PET, by research various species like Vibrio and Ideonella sakaiensis which can degrade PET have been identified. There are certain species of microbes which can decompose rubber from garbage.
a) How are aquatic organisms affected by oil spills in the ocean?
b) Which type of chemical compounds are degraded by microbes used for
clearing oil spills?
c) Name any two species of microbes which can degrade rubber from
garbage.
