Consider this northern site of primary succession following the retreat of a glacier. As we move from left to right, describe some improvements in the abiotic factors that support plant growth. A) change in climate over time B) less competition for water resources due to biodiversity C) improved soil quality: increased humus and water retention D) increased population density resulting in decreased pathogens

Answer: C. improved soil quality: increased humus and water retention.

Explanation:

An ecological succession brings change in the type of living species residing in an ecosystem with respect to changes that occur in the abiotic (non-living factors) with respect to time.

A region affected by a retreating glacier will not be suitable for the growth of living species. The soil may be lacking minerals and will be in the permafrost condition. So for the initiation of succession the improvement in soil an important abiotic factor is required. The improved soil quality will allow the accumulation of organic and inorganic minerals by physical and biological processes. This will help in formation of humus and water retention.

Which factor do oceanographers measure in order to determine the salinity of ocean water

The salinity of ocean water can be determined by measuring the conductivity of the water. The characteristics of water such as salinity, depth, temperature, density can be defined by the instrument called Conductivity Temperature Depth instrument. This instrument is placed in water which is to be measured. As this instrument is lowered into the water it continuously records the conductivity, temperature and depth of the water. The electric current is flowed through the water and as we know salt water is a good conductor of electricity it will pass the current fast. Using this technique oceanographers determine the salinity of water.

Hemophilia, color blindness, and duchenne muscular dystrophy occur more often in males than females. why? a these traits are carried only on the x chromosome and since there is no matching gene on the y chromosome, the traits are expressed more readily in males. b these traits are carried only on the x chromosome. c testis-determining factor (tdf causes these diseases. d these diseases develop due to the lack of estrogen and progesterone. e since there is no matching gene on the y chromosome, the traits are expressed more readily in males.

Answer:

a) these traits are carried only on the x chromosome and since there is no matching gene on the y chromosome, the traits are expressed more readily in males.

Explanation:

Hemophilia, color blindness, and duchenne muscular dystrophy are disorders which are caused by X-linked recessive mutations which means that even if a mutation occurs in a gene of only one X chromosome then the phenotype will be expressed in the males because they are hemizygous for the gene. By hemizygous we mean to say that males have one X and one Y chromosome so a gene present on X chromosome will not find match on the Y chromosome and the mutation will express readily.

In contrast to this, in case of females who have two X chromosomes, the mutation in one X chromosome may be suppressed by another X chromosome in heterozygous condition i.e. if another X chromosome has healthy gene (wild type gene). In case of females the diseased phenotype will only appear if they are homozygous for the mutation.

What did Mendel's cross pollination of pea plants prove A crossing a tall plant with a tall plant will always results in a tall plant B all the cells in an organism carry the same hereditary factors C inheritance of certain factors is dependent upon the genetic code D certain factors are dominant and other factors are recessive

Answer: The correct answer is- D certain factors are dominant and other factors are recessive.

Mendel was interested in knowing the offspring that is produced from the cross pollination (that is from two different plants) as he wanted to study different traits of pea plant.

For doing so, he first removed the anthers of one plant (to prevent self pollination) and then transferred the pollens of one plant into the stigma of another plant.

When he allowed the cross pollination of purebred pea plant with other plant, he observed that some factors are dominant (such as tall height of pea plant, which masks the expression of recessive factors) and other are recessive (such as dwarf height of pea plant).

Thus, option D) is the right answer.

An objects position is always defined relative to a reference point. If the object changes position, its motion can be described as moving in some direction in relation to this reference point. If the relative position of a diver Is begin described as below a certain reference point midway through a dive, what reference point is most likely being used A. The bottom is the swimming pool B. The diving board C. Other swimmer in the water D. The far side of the swimming pool

The position of the diver is described as "below a certain point"; therefore, the reference point must be above the diver. For a diver in the middle of his dive, the bottom of the pool, the other swimmers and the far side of the swimming pool are likely to be below the diver, or at level with the diver at most. Out of the options, the only point of reference that is likely to be above the diver is B. the diving board.

Consider a wetland habitat. Imagine a very hot summer with little rain. What would be the density dependent limiting factor for the populations of all animals living here

The density dependent limiting factor for the population of all animals living there is the supply of water or watering holes that are available within the environment. Sometimes, animals decrease in their population when water resources are not available. Almost all living organisms on Earth are dependent on water and cannot survive without, rising temperatures can give way to such scarcity.

Factors that are manipulated during an experiment procedure

Science is an organized way of using evidence to learn about the natural world.

The goal of science is to investigate and understand the natural world, to explain events in thenatural world, and to use those explanations to make useful predictions.

The Scientific Method Itself:
I. Observations:

Whether they start with a problem or not, scientists make careful observations.

Observations are a way to collect data (recorded observations or information) about events or processes in a careful, orderly way, using the senses (sight, hearing, touch, taste and smell).

Two types of data include:

a) Quantitative data: Are observations which collect data that can be directly measured or counted.

b) Qualitative data: Are observations involve making careful descriptions or drawings and do not involve numbers.

Inference: A logical interpretation of an observation based on prior knowlege. An educated guess as to what is occurring.

II. Hypothesis:
A proposed scientific explanation for a set of observations. Scientists devise hypotheses based on logical inferences, prior knowledge and informed, creative imagination.

Hypotheses may be tested by controlled experiments, or by collecting additional data.

III. Controlled Experiment:
A way to test a hypothesis by testing a single variable by changing it while keeping all other variables the same.

Variable: Any factor during an experiment that could change and affect the results (Examples: Temperature, pressure, amount of light, color of light, human error, etc......)

Manipulated variable: The factor in an experiment that is deliberately changed to test the hypothesis.

Controlled variable: any factor during an experiment that a scientist purposely keeps the same.

During the experiment, a scientist divides the tests into 2 groups, the control setup and the experimental setup.

Experimental setup: The part of the experiment that contains the manipulated variable.

Control setup: The part of the experiment that does not contain the manipulated variable. It may be called the placebo.
