Explanation:

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.

Thus, a and f are the correct options.

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:

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.

Question 1

a) What is Emma’s recommended daily protein requirement? 50.4 grams

b. What percentage of Emma’s current total energy intake comes from protein?

13.33%

Does it fall within the recommended range in terms of the percentage of total energy intake?

Yes it does fall within the recommended range in terms of the percentage of total energy intake which is 10 - 35%

c. Emma is concerned about her intake of the essential fatty acid omega-3. Can you suggest for her two food items that she can include in her diet?

i. Walnuts

ii. Flaxseeds.

Question 2

2. Rank the following oils/fats according to the ease with which they would spoil, and explain how you arrived at your conclusion: coconut oil, flaxseed oil, olive oil.

According to the ease of spoilage:

Flaxseed oil – Coconut oil – Olive oil

Explanation:

a) What is Emma’s recommended daily protein requirement?

RDA of protein for adults is given as 0.8 g per kilogram of body weight of 0.36 per pounds of body weight.

Therefore, Emma's recommended daily protein intake is calculated as:

Her body weight in pounds × 0.36

Emma's body weight = 140 pounds

140 pounds × 0.36

= 50.4 grams.

Therefore, Emma’s recommended daily protein requirement is 50.4 grams of protein.

b. What percentage of Emma’s current total energy intake comes from protein?

Since 4 calories is the energy received from 1 gram of protein

In the question, we are told that Emma takes a daily intake of 40 grams of protein.

Therefore,

1 gram of protein = 4 calories

40 grams of protein =

40 × 4 = 160 calories.

The Lacto Ovo vegeterian diet, Emma is on gives her 1200 calories per day.

Hence, the percentage of Emma’s current total energy intake comes from protein is calculated as:

(Emma's daily energy in calories from protein ÷ Daily energy in calories supplied by her Lacto ovo vegetarian diet) × 100

= (160 calories ÷ 1200 calories) × 100

= 13.33%

c.

Omega -3- fatty acids are fatty acids that are very good for the body. Even though they are fatty acids, they do not clog the arteries thereby helping in preventing the occurrence of heart disease. They also lower the blood pressure in the body.

Foods that contain omega -3- fatty acids are fatty fish such as Salmon, Mackerel as well as nuts and seed like Walnuts, Flax seeds ( Flax seed oil).

Emma is concerned about her intake of the essential fatty acid omega-3. Can you suggest for her two food items that she can include in her diet?

Since Emma takes nuts, 2 food items she can include in her diet that are rich in Omega-3 fatty acids are:

i. Walnuts

ii. Flax seeds

2. Rank the following oils/fats according to the ease with which they would spoil, and explain how you arrived at your conclusion: coconut oil, flaxseed oil, olive oil.

According to the ease of spoilage:

Flaxseed oil – Coconut oil – Olive oil

Flaxseed oil spoils more easily than coconut oil and coconut oil spoils easily than Olive oil. This is based on their exposure to heat.

When heated up, Flaxseed oil breakdown more easily , followed by coconut oil.

Coconut oil has the tendency to become cloudy after been stored for a while.

This is why even though we can use but Flaxseed and Coconut oil for cooking , Olive oil is still the best because it has the tendency to withstand a large amount of heat and it is heat stable as well as more stable at even room temperature.

Answer:The cycling of matter is among the three main factors upon which life on the earth depends. Concerning the cycling of matter, because there are only finite amounts of nutrients available on the earth, they must be recycled in order to ensure the continued existence of living organisms

Explanation:

The cycling of matter, such as the carbon cycle, is essential for providing the materials necessary for life. These biogeochemical cycles ensure readily available elements for organisms to use, preventing essential elements for maintaining ecosystem sustainability.

The cycling of matter is fundamentally important to all living things as it ensures the continuous availability of essential elements like carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur. Biogeochemical cycles involve both biotic and abiotic components and are essential for life on Earth because they provide the materials necessary for organisms to construct their bodies, carry out life processes, and maintain ecosystem sustainability.

The carbon cycle, for instance, plays a critical role in the fixation of atmospheric carbon dioxide into biomass through photosynthesis. This is a primary pathway for solar energy to be captured and converted into chemical energy that can be used by organisms.

Without the cycling of matter, essential elements could become trapped in unavailable forms, hindering the survival of living organisms. For example, if carbon were to become sequestered in crustal rocks and sediments without being recycled, living organisms would lack the raw materials needed for vital organic compounds. Also, the recycling of elements like phosphorus and sulfur is crucial as they undergo various state changes and move through the atmosphere, water, and soil, affecting many aspects of the ecosystem.

Through these cycles, matter is conserved within the biosphere, continually moving between living organisms and the environment in a balanced manner. Such processes are necessary for the production of food, energy storage, and the regeneration of raw materials which are all required for the persistence and functioning of life on Earth.

Answer:

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.

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%.

Answer:

The gametes are haploid, having half the number of cells as compared to somatic cells. The gametes or cells produced by the organism will have 6 chromosomes if the organism has 12 chromosomes.

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.
