Answer:

Stomata, Guard cells.

Explanation:

Angiosperms are known as flowering plants that contain their seeds in fruits. They are including a variety of plants such as submerged, aquatics, trees, herbs, etc. Two main parts of an angiosperm leaf are:

Stomata: They are tiny pores present on the plant epidermis, these small openings on the leaves allow gas exchange to occur in plants.

Guard cells: These cells help to controls stomata opening and closing, also helps to stimulate gas exchange and control transpiration in plants.

Final answer:

The angiosperm leaf has a blade for photosynthesis and a petiole for support and nutrient transport. Deciduous plants drop leaves to conserve water, while evergreens have needle-like leaves to reduce water loss. Variation in leaf structure among angiosperms is often an adaptation to environmental conditions.

Explanation:

The angiosperm leaf consists of two main parts: the blade (or lamina) and the petiole. The blade is the broad, flat part of the leaf which contains a high concentration of chloroplasts, making it the primary site for photosynthesis.

The petiole is the stalk that attaches the leaf blade to the stem at a node, providing support and transporting water and nutrients between the leaf and the rest of the plant.

Different environmental conditions lead to variations in leaf structure and function. Angiosperms exhibit a wide range of leaf shapes, margins, and venation patterns, which are often adaptations to specific climatic and environmental factors such as light, water availability, and temperature.

A region of DNA consisting of the promoter and operator sequences needed to regulate one or more structural genes.

Explanation:

An operon is a part of the the DNA that is found in bacteria or viruses which function in transcription and genetic regulation. Operon is under control of an operator, consist of promoter, regulator and structural genes. Operon is normally under the control of a single operator in which genes coding for protein are clustered along the DNA.

Answer:

A

Explanation:

Answer:

Analogous structures are structures which serve similar function in different organisms and evolved independently in two living organisms while homologous structures are the structures which are similar in related orgnanism due to inheritance.

The wings of Pterodactyl, bats and birds are conisdered as analogous structure. they are similar in structure and same in function and evolved independently in the two groups of animals.

Bones in  forelimbs of pterodactyl, bats and birds are  considered homologous  structures as they inherited the pattern from a common ancestor and have different functions.

Answer:

B) the number of different kinds of organisms present

The biodiversity in an area is the variety of life, including the number of organism species and their relative abundance. Ecologists measure biodiversity and recognize its importance for human survival and ecosystem health. Biodiversity also encompasses genetic and ecosystem diversity.

The biodiversity in an area refers to the number of different kinds of organisms present (option B). More specifically, it is the variety of life and its processes, including the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur. Biodiversity is crucial as it affects the survival and well-being of human populations. It impacts our health, our ability to produce food through agriculture, and maintain functional ecosystems.

Traditionally, ecologists measure biodiversity by considering the number of species and their relative abundance in a particular area. This area could be as small as a local habitat or as large as the entire biosphere. Species richness is a term describing the number of species in a habitat and can vary globally, often higher near the equator and lower near the poles. Factors such as island size and distance from the mainland, as per island biogeography studies, also influence species richness.

Biologists are expanding measures of biodiversity to include genetic diversity and ecosystem diversity, which help in focusing conservation efforts to preserve vital elements of biodiversity. Genetic diversity is the variety of genes within a population, and it is essential for a species' adaptation to environmental changes and new diseases. Ecosystem diversity refers to the variety of ecosystems in an area, with the loss of an ecosystem leading to the loss of species interactions and biological productivity.

The distance of an asteroid from the Sun can be measured in Astronomical Units (AU), which is the average distance between the Earth and the Sun. To find the exact distance, we would need to know the specifics of the asteroid's orbit.

The distance of an asteroid from the Sun can vary, depending on its current position within its orbit. The Astronomical Unit (AU) is used as a standard measure of distance in Astronomy. One AU is approximately equal to the average distance between Earth and the Sun, about 93 million miles or 150 million kilometres. To determine how far an asteroid is from the Sun in AU, we would need to know the specifics of its orbit. For instance, if we know the asteroid's semi-major axis (average distance from the Sun), we can say the distance in AU.

https://brainly.com/question/36946155

Final answer:

To find the average distance of an asteroid from the Sun in astronomical units, given its orbital period of 8 years, one can apply Kepler's Third Law. This gives us an average distance of approximately 4 AU.

Explanation:

The student asked, "What is the average distance from the Sun (in astronomical units) of an asteroid with an orbital period of 8 years?" To determine this, we can use Kepler's Third Law of Planetary Motion, which states that the square of the orbital period (P) of a planet is directly proportional to the cube of the semi-major axis of its orbit (a), where P is in years and a is in astronomical units (AU). For Earth, P is 1 year and the distance a is 1 AU by definition.

If the asteroid's orbital period is 8 years (P = 8), then we can calculate the semi-major axis (a) of the asteroid's orbit as follows:

P² = a³

8² = a³

64 = a³

a = ∛64

a ≈ 4 AU

Thus, the average distance of the asteroid from the Sun is about 4 AU.

Answer: C. That jellyfish have stinging cells, while comb jellies do not

Explanation:

Comb Jellies to the untrained eye are the same as Jellyfish but as the question says, they are different in that they belong to different phyla.

The Comb Kelly belongs to the Ctenophora Phylum while the Jellyfish belongs to the Coelenterate phylum.

Perhaps the largest difference between them is that Ctenophora do not have stinging cells as opposed to members of the Coelenterate Phylum that do.

Jellyfish and comb jellies are in different phyla because jellyfish have stinging cells for capturing prey while comb jellies do not. Hence, option C is correct.

Ashley should write that jellyfish and comb jellies belong to two different phyla because jellyfish have stinging cells, while comb jellies do not. Specifically, jellyfish are part of the phylum Cnidaria, characterized by their stinging cells called nematocysts which they use for capturing prey. On the other hand, comb jellies belong to the phylum Ctenophora, and they lack these stinging cells. Instead, comb jellies use colloblasts or sticky cells to capture prey. Additionally, while both creatures are invertebrates and live in aquatic environments, they have different biological structures and genetic makeup that necessitate their classification into separate phyla.

Answer:

d = st

Explanation:

t =

s =

t =

s = dt

d = st

d =

The formula that represents correct variation of the formula for speed would be d = st, where d = distance traveled by an object, s = speed of the object, and t = the time taken by the object.

Speed is defined as the distance traveled by a moving object per the time taken by the object to complete the distance. Mathematically, it is represented as:

Speed (s) = [tex]\frac{distance (d)}{time (t)}[/tex].

Hence, s = [tex]\frac{d}{t}[/tex]

If the formula is cross multiplied, then we will have;

d = st

Answer:

A, B, E

t = d/s, s = s/d, d = st

Answer:

Hydrophytes are defined as the plants that grow in aquatic environment.

Xylem and phloem are part of transport system in plants. Water and minerals from roots to leaves are carried by Xylem and sugar and other organic nutrients are carried by Phloem.

Hydrophytes grow in water, so have access to abundant water. It helps water to diffuse easily in hydrophytes and hence require less number of xylem for water transport.

So, number of xylem are less than the number of phloem in hydrophytes plant.

Answer:

3/32

Explanation:

The probability would be 3/32

From the illustration:

EeWw and EeWw were crossed  (Assuming both traits are autosomal)

EeWw   x   EeWw

Progeny :

1 EEWW  - unattached earlobe with widows peak

2 EEWw -  unattached earlobe with widows peak

2 EeWW -  unattached earlobe with widows peak

4 EeWw -  unattached earlobe with widows peak

1 EEww -  unattached earlobe with non-widows peak

2 Eeww -  unattached earlobe with no-widows peak

1 eeWW  - attached earlobe with widows peak

2 eeWw - attached earlobe with widows peak

1 eeww - attached earlobe with no-widows peak

Generally, the probability of obtaining a male or a female in a cross is 50/50 or 1/2.

From the crossing result, the probability of having attached earlobe and widows peak hairline is 3/16.

Hence, the probability of obtaining a boy with attached earlobes and widows peak airline:

1/2 x 3/16 = 3/32.

Final answer:

The probability of a child having attached earlobes and a widow's peak hairline from parents with genotypes EeWw is calculated using a Punnett square, resulting in a 18.75% chance or 3/16 probability for these traits to occur together.

Explanation:

In humans, unattached earlobes are dominant over attached earlobes, and widow's peak hairline is dominant over non-widow's peak hairline. When solving for the probability of a child inheriting attached earlobes and a widow's peak hairline from parents with genotypes EeWw, we use the Punnett square method.

In a two-trait Punnett square, each parent can produce four types of gametes: EW, Ew, eW, and ew. The child must inherit an e from both parents for attached earlobes and at least one W for a widow's peak. The Punnett square for this cross would be a 4x4 grid, with each cell representing a possible genotype of the offspring.

After filling out the Punnett square, we find that the offspring will have a 1/4 chance (probability of 25%) for attached earlobes and a 3/4 chance (probability of 75%) for the widow's peak. The combined probability of having both attached earlobes and a widow's peak is the product of the individual probabilities, which is (1/4) × (3/4) = 3/16 or 18.75%.

The answer is indeed option D

Answer:

If plants are grown in soil containing worms, then the plants will grow faster

Explanation:

because worms dig tunnels in the ground.  These tunnels create a path for air which is beneficial for the plant.  Also, worms create nutrient rich fertilizer for the plant

Worms are considered the good friends of the farmers because worms increase the fertility of the soil due to which there is an increase in crop production. Hence plants grown in soil containing worms will have higher faster growth.

As discussed above worms are friends of the farmers because they are decomposers, worms convert the dead and decaying material into humus which is rich in organic and inorganic nutrients.

These organic and inorganic nutrients are absorbed by the plants through the roots by the soil which are essential for good growth and proper development.

High growth in the plants results in a high yield of crops and foods, vegetables, etc.

The characteristic that are present in bacteria is lack a nucleus, are prokaryotes. The correct options are a and f.

Prokaryotes are the basic creatures without a nucleus or other organelles in their cells. Bacteria and archaea, two distinct groupings of prokaryotes with allegedly independent evolutionary histories, are separated into.

The majority of prokaryotes are tiny, single-celled creatures with a straightforward structure.

Since prokaryotic cells lack a membrane-bound nucleus, eukaryotic cells are the main difference between these two types of creatures. Eukaryotes store their genetic material in their nuclei.

Bacteria are common, largely free-living organisms that frequently only have one biological cell. They make up a significant portion of the prokaryotic microbial kingdom. Prokaryotes, which lack a nucleus, are a hallmark of bacteria.

How long is the G2 phase = 6hours

Explanation:

Cell cycle undergoes various stages  during mitotic cell division.

Normally cells are arrested in the resting phase G0 but as the cell division starts it undergoes G1 the growth phase then it undergoes S phase called the Synthesis phase in which the DNA synthesis occurs. Then it undergoes G2 Phase and is the shortest phase while G1 is the longest phase of the cycle. G2 normally lasts for 3-4 hours so here it may take 2.775 hours as due to presence of Thymidine the synthesis of DNA occur at high level so it contains higher levels of cellular DNA than in the G1 . so it will take  6hours G2 phase to occur.

The G2 phase will take 6 hours.

We can arrive at this answer because:

Thus, if the 3H thymidine radiolabel can be visualized after 6 hours and it will be a participating element in cell division, we can agree that the G2 phase will last 6 hours.
