Check all the boxes where the vocabulary word correctly matches its
science definition?
Equilibrium: a system where forces are in balance
O
Climax community: the end of a succession resulting in a stabilized community
o
Succession: the act of winning in life
Primary Succession: colonization of an area that has not been previously occupied by
a community, e.g. newly exposed rock
Pioneer Species: the first organisms to live on rocky surfaces, e.g. lichens, moss,
algae, and fungi
Secondary Succession: colonization following a major disturbance, such as a fire or a
flood
Answer:
Climax community, primary succession, pioneer species, secondary succession.
Explanation:
Equilibrium with regards to succession occurs as "a state of dynamic equilibrium in a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, but this factors are subject to gradual changes through natural succession."
Succession: the process by which the structure of a biological community evolves over time.
A region with a variety of organisms like tiger, fish, rabbits, birds, insects, etc.,
have a high level of
genetic diversity
species diversity
ecosystem diversity
none
Answer:
Species diversity is the right answer.
Explanation:
It is stated that the region is full of different organisms. An organism is defined as an individual animal, plant, or single-celled life form. All this variety of a region makes an ecosystem so having multiple ecosystems in a specific region is out of hand.

Which of the following explains one of the ways plants and animals depend on each other?
A
Animals make minerals, which plants take in through their roots and pass up to their stems.
B
Animals release water vapor when they breathe, which plants take in through their leaves.
C
Animals make their own food, which plants take in through their roots and pass to their leaves.
D
Animals release carbon dioxide when they breathe, which plants take in to help make food.
Answer:
Animals release carbon dioxide when they breathe which plants take in to help make food
Animals release carbon dioxide when they breathe which plants take in to help make food. So the correct option is D.
Why do animals and plants depend on each other?
All species present on earth depend on each other for performing basic life processes. Humans are not able to survive beyond a particular range of temperature and pressure. For all the species to survive, a healthy environment is required.
Plants and animals are dependent on each other. This is because, in ecological systems, no species can survive alone. Animals are dependent on plants. Plants are the primary producers in our ecosystem. They produce food that is consumed by primary consumers and the primary consumers are consumed by secondary consumers.
Plants use carbon dioxide for photosynthesis and it results in the production of oxygen. This is used by animals for the process of respiration.
Plants depend on animals for several reasons. These can be fruit and seed dispersal, pollination, and also for the carbon dioxide that the animals produce. Thus, both plants and animals are interdependent on each other.
Therefore, the correct option is D.

Which contributes to the movement of air masses
Answer:
The Movement of Air Masses: transporting warm air northward and colder air southward. Counterclockwise winds associated with cyclones transport heat and moisture from lower to higher latitudes and play a significant role in the movement of air masses. A warm front marks the leading edge of this warm, moist air mass.

What are the five main functions of nematodes in soil?
Answer:
Nematodes are the bacterial feeders, fungal-feeders, plant parasites, predators, and omnivores.
Explanation:
hope this helps :)
Answer:
Nematodes play an important role in nutrient cycling. In particular, they play a key role in the nitrogen cycle. Nematodes take in nitrogen and excrete it in a form that plants and bacteria can use.
Nematodes graze on bacteria, plants, and other soil organisms. In ecosystems, nematodes play a major role in regulating the populations of their prey organisms.
Nematodes carry fungi and bacteria in and on their bodies. As nematodes move through the ecosystem, they disperse the bacteria and fungi.
Nematodes are a part of food chains and food webs. They are an important food source in many ecosystems.
Nematodes impact the health of other organisms. Some help prevent, or suppress, disease by eating other disease-causing organisms. Other nematodes cause disease in plants and animals.

The shrimp population will decrease which will cause an increase in the squid population.
C.
The shrimp population will decrease which will cause an increase in the sperm whale population.
D.
The shrimp population will increase which will cause a decrease in the sperm whale population.

I believe the answer is A because if shrimp eat phytoplankton, and squid eat shrimp this should work. I am not positive but I hope this helps.
What happens during interphase that allows the two resulting cells to be the same as the
original cell?
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. ... Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

Answer:
A
Explanation:
A: Venus rotates far more slowly than Earth
Look at the column that says Period of Rotation.
Venus has a rotation period of 243 days.
Earth has a rotation period of about 24 hours.
243 days is much longer than 24 hours, so this is true.
B: Venus's year is longer than Earth's.
The year is also another way to say Period of Revolution.
Venus's is about 224 days.
Earth's is about 365 days.
Venus's is actually shorter, so this is false.
C: Mercury is approximately twice the size of Earth.
Let's look at the Equatorial Diameter column.
Mercury's is 4,880 km.
Earth's is 12,756 km.
Mercury's is much smaller than Earth's, so this is false.
D: All of the above.
Since B and C are both not true, this is incorrect.
Therefore, the correct answer is A: Venus rotates far more slowly than Earth.
Anya and Greg are working in their research laboratory. Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd. How can Anya explain her reasoning? In two out of 50 times, the mouse has the alleles DD or Dd. The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. The mouse is twice as likely to have the alleles DD than it is to have the alleles Dd. There are two more possible outcomes besides the mouse having DD or Dd alleles.
Answer:
Option B: The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd.
Explanation:
Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd.
She can explain her reasoning by saying that both pairs of alleles (DD and Dd) has equal chance of being expressed i e, the probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. Both pairs each has 0.5 chance of occuring.
Answer:
Explanation:
A Dominant Allele is an Allele that express itself.
DD- this represent a dominant homozygous allele
Dd- represent a dominant heterozygous allele
When an individual with DD is crossed with Dd we will have DD,Dd,DD,Dd
Phenotypic ratio is 2:2
i.e homozgous dominant crosses with heterozygous dominant
which means both DD and Dd have 50% chance of occuring in the genotype and the probabality is the same.
Note that in the phenotype of an individual with homozygous dominant (DD) is the same phenotype with heterozygous dominant(Dd)

how does blood volume affect blood pressure
Answer:
Changes in blood volume affect arterial pressure by changing cardiac output. An increase in blood volume increases central venous pressure. This increases right atrial pressure, right ventricular end-diastolic pressure and volume.
Explanation:
In the following exercise you will be given a wild type (ancestral) DNA code that you will transcribe and translate into an amino acid sequence (remember start codons). In addition to the wild type code, you have been given five mutated sequences of the wild type code that you will also transcribe and translate. For each mutation you will determine the mutation type (substitution, insertion, deletion) and effect (silent, nonsense, missense, frameshift-missense, frameshift-nonsense) by comparing to the wild type. Wild type template strand:
3'TGTACTTCAAACCGATT5"
mRNA-
AA Seq.
Answer:
Wild type template strand
3'TGTACTTCAAACCGATT5'
Wild type template DNA strand after transcription give following mRNA sequence
5’ACAUGAAGUUUGGCUAA3’
This mRNA has five codons; out of five, four codons (AUG, AAG, UUU and GGC)encode aminoacid and one is stop codon (UAA). Therefore, after translation this mRNA gives following amino acid sequence
Methionine-Lysine-Phenylalanine-Glycine
