Two plant groups you could look at are land-based plants and water-based plants.

Explanation:

Land-based plants:

Land-based plants are plants that can be found on land. They tend to be taller in order to absorb as much sunlight as possible. Land-based plants often have roots that are rooted in soil, and take in water and nutrients from there. Land-based plants taken in oxygen and carbon dioxide directly from the atmospheric air around them. In terms of the location of their stomata, stomata can be found on the underside of leaves, where they take in carbon dioxide and release oxygen.

Water-based plants:

Water-based plants can be found either submerged or floating on water. They tend to be broader instead of taller. For instance, their leaves will be broader in order to absorb maximum sunlight. This is because (especially for completely submerged water plants), light does not penetrate as deeply into water, leaving the plant with less light energy to photosynthesize. Water-based plants often have roots that either dig into the soil if they are found at the ocean floor, or hang freely in the water if they float on water surfaces. Unlike land-based plants, water plants, especially those that are fully submerged, take in dissolved carbon dioxide and oxygen gas in the water instead of from the air and atmosphere. The stomata of water-based plants are often found on the upper side of their leaves, in order to have better access to atmospheric oxygen and carbon dioxide.

Some human white blood cells help destroy pathogenic bacteria by *
(1) causing mutations in the bacteria
(2) engulfing and digesting the bacteria
(3) producing toxins that compete with bacterial toxins
O (4) inserting part of their DNA into the bacterial cells

Answers

Answer:

2

Explanation:

They either engulfy and digest pathogens(phagocytosis) or produces antibodies.

Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

Thus, By engulfing pathogenic bacteria through a process known as phagocytosis, some human white blood cells, notably phagocytes like neutrophils and macrophages, aid in the destruction of pathogenic germs.

These phagocytes have the capacity to identify and bind to bacteria, creating a phagosome—a membrane-bound compartment—around the bacterium.

The phagosome then joins forces with lysosomes, which are organelles that carry digesting enzymes, to create a phagolysosome. The bacteria are exposed to the lysosomal enzymes inside the phagolysosome, which causes them to break down and die.

Thus, Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

Ophrys sphegodes, the early spider orchid, has flowers with yellow-green sepals and petals and one highly modified, velvety brown central petal at the base of the flower. There is single male anther is found at the tip of the column. The stigma is on the underside of the column just below the anther.

Required:
a. Is the flower complete or incomplete?
b. Is the flower perfect or imperfect?
c. Is the flower radially or bilaterally symmetrical?

Answers

Answer and Explanation:

a. This is a complete flower. Complete flowers are those formed by chalice, corolla, androecium and gynoecium. In the case of the flower presented above, we can see that it has gynoecium because it has a stigma that is part of the gynoecium composition. We can also see that she has androecium, because she has an anther that is part of the composition of androecium. The flower also has a corolla and chalice, since the chalice is formed by the sepals and the corolla by the petals.

b. This is a perfect flower, as we can see that androecium and gynoecium are present in the same flower. Imperfect flowers are those with only androecium or gynoecium.

c. The flower has bilateral symmetry, which is common in all orchids. This type of symmetry allows the flower to only be divided into two equal parts. Radial symmetry, on the other hand, allows flowers to be divided into many equal parts.

According to the diagram below, what type of organism converts atmospheric nitrogen (N2) to ammonia (NH3) and then to nitrites (NO2-) and nitrates (NO3-)?

Answers

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.

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:

heterozygous means there are two different alleles. So the trait would be written as Bb. I can't write the other option because it counts it as a swear word but it means that there are two identical alleles. So it would be written as BB

Answer:

False

Explanation:

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.

Answers

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: 123    

Autosomal 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 + mmXY

     Females

6/8 = 3/4 = 75% Wild-type cats → MMXX + MmXX 2/8 = 1/4 = 25% Mutated cats → mmXX

     Males

6/8 = 3/4 = 75% Wild-type cats → MMXY + MmXY2/8 = 1/4 = 25% Mutated cats → mmXY
