Which energy pyramid accurately represents the amount of energy at each level of
this food web?
Owls
Skunks
Mice
Grasshoppers
Grass
Answer:
it's owls
Explanation:
Energy pyramid accurately represents the amount of energy at each level of this food web Owls.
What is Energy pyramid?
The energy present within the trophic layers of an ecosystem is called an energy pyramid, sometimes referred to as a trophic or ecological pyramid.
The producers are located in the base of the pyramid, which is also its greatest level. The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
Even though it cannot be produced or destroyed, energy is emitted as heat at each level. Only 10% of energy is essentially transferred from one level to the next.
Therefore, Energy pyramid accurately represents the amount of energy at each level of this food web Owls.

Explanation:
If u and y are two variables such that
du
= 4v - 3. and u = 5 when v = 2,
du/dv
find u in terms of v.
Answer:
5
Explanation:
The value of u is 5 in term of v by putting the value o v which is 2 in the formula that is du = 4v - 3. Putting the value of v = 2 we get, du = 4(2) - 3. --- du = 8 - 3. ---- du = 5. we are able to solve the question due to the presence of v value. If the v value is not present then we can't find the value of u in term of v. So we can conclude that the value of u in term of v is 5 if we put the value of v in the formula.
Which class of Lever is being described if you are standing on tiptoes and if: The Fulcrum is at the metatarsal and phalanges, which is at one end of this lever on the anterior side of the body. The Load is your body weight which is in the middle of this lever. The Effort is exerted by the gastrocnemius and soleus muscles at the calcaneal (Achilles') tendon on the other side of this lever on the posterior side of the body.
Answer:
Second class lever
Explanation:
A second class lever is when the resistance ( load/weight ) is placed in between the axis ( Fulcrum which is formed by the metatarsal and Phalanges ) and the force ( Achilles tendon ) that is applied to the lever. hence the class of lever being described is a second class lever
There are three classes of lever ( 1st class, 2nd class and third class ) but The most common lever found in Humans are the 3rd class levers. but standing on tiptoes by an individual is a perfect example of a 2nd class lever found in a Human.
The Load being the body weight being and in the middle of this lever is
referred to a the second class lever.
The second class lever has the load in between the effort (force) and the
fulcrum. A common example is the wheelbarrow which has the load in the
middle.
In this scenario, the load which is the body is between the
effort(gastrocnemius and soleus muscles) and the fulcrum is the phalanges
which is a characteristic of a second class lever.

Explanation:
Fresh steak is said to have both negative and positive redox potential. Discuss how the redox potential affects the microbial ecology of the food
Answer:
Increases redox potential decreases microbial growth inside food.
Explanation:
The redox potential is considered as one of the most complex indicators of the physical conditions of microbial cultures. The measurement of redox potential could be very useful for the determination of qualitative and quantitative parts of the microbial contamination. During the bacterial growth, the redox potential of the medium decreases. Redox potential is a measure of the tendency of a biological species which can be acquire or lose electrons through ionization. If the redox potential of the medium is increases, there will be lower growth of microbes in the food and vice versa.
On the planet Feline, there are only cats. For one particular phenotype, Myles, there are two manifestations: either the cats like jazz music (the wild type phenotype) or they do not (the mutant phenotype). Under the assumption this phenotype is determined by a single gene with two alleles, and given that a mating of two wild-type cats produces the following number of offspring: Female, wild-type: 341; Male, wild-type: 369; Female, Myles: 121; Male, Myles: 123. The mode of inheritance most consistent with these data is:________
A. Autosomal dominant.
B. Two-locus inheritance.
C. Sex-linked recessive.
D. Autosomal recessive.
E. Two-locus dominant.
Answer:
D. Autosomal recessive.
Explanation:
Available data:
One diallelic gene codes for the phenotype MylesOne allele expresses the wild type phenotype → like jazz musicThe other allele expresses the mutated phenotype → don´t like jazzCross: Between two wild catsF1) Female, wild-type: 341; Male, wild-type: 369; Female, Myles: 121; Male, Myles: 123Autosomal recessive inheritance characterizes because the mutated gene locates in one of the 22 non-sexual, somatic chromosomes. To express the phenotype, an individual must carry two copies of the mutated gene. For this reason, the recessive allele must be present in both the male/father and the female/mother.
In the exposed example, the numbers among the progeny are 341:369:121:123. These values approximate a phenotypic ratio 3:1 for females, and for males. This ratio suggests that the cross was performed between two heterozygous individuals.
Let us name the alleles M and m, dominant and recessive respectively. The cross would be like follows
Cross: wild-type male x wild-type female
Parentals) Mm XY x MmXX
Gametes) MX, MY, mX, mY MX, MX, mX, mX
Punnett Square) MX MX mX mX
MX MMXX MMXX MmXX MmXX
mX MmXX MmXX mmXX mmXX
MY MMXY MMXY MmXY MmXY
mY MmXY MmXY mmXY mmXY
F1) Whole progeny
12/16 = 3/4 = 75% Wild-type cats → MMXX + MmXX + MMXY + MmXY4/16 = 1/4 = 25% Mutated cats → mmXX + mmXYFemales
6/8 = 3/4 = 75% Wild-type cats → MMXX + MmXX 2/8 = 1/4 = 25% Mutated cats → mmXXMales
6/8 = 3/4 = 75% Wild-type cats → MMXY + MmXY2/8 = 1/4 = 25% Mutated cats → mmXY

According to the diagram below, what type of organism converts atmospheric nitrogen (N2) to ammonia (NH3) and then to nitrites (NO2-) and nitrates (NO3-)?
Answer: Nitrogen-fixing Bacteria
Explanation:
In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.
Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.
