This nice sample from the tonto national monument, arizona, is hard stone now, but it once was soft sediment, and it records formation and "fossilization" of mud cracks. the light was shining along the arrow, as shown, making shadows, some of which are indicated by the arrows. is this sample upside-down (you are looking at the side of this sample that was down when the sediment was soft) or right-side up (you are looking at the side of this sample that was up when the sediment was soft)?

Answers

Answer 1
The answer is upside-down. Mud cracks spread downward keen on soft sediment. When more sediment is eroded in, this second layer will seal the cracks underneath. Later, after the layers have toughened, the rock may be rotated upside-down and then the layers cracked. If you see edges in a mud-crack pattern, you are seeing at the side of the second layer that initially was down. You can tell that this shows edges, and not holes, through the shadow, the edges have a well-lit on one side and a shadow on the other, while holes have light and shadow on the similar side.

Study the diagram, which represents the general equation for photosynthesis. What do the letters Y and Z represent?

Y - glucose
Z - oxygen

Y - glucose
Z - carbon dioxide

Y - carbon dioxide
Z - hydrogen

Y - carbon dioxide 
Z - oxygen

Answers

Answer:

The correct answer is Y - glucose, Z - oxygen

Explanation:

In photosynthesis, plants- and also other organisms- take carbon dioxyde (CO₂), water (H₂O) and light (which is absorbed by chlorophyll pigments, those give plants their green color), and they convert inorganic materia in organic materia (chemical energy) in form of sugar. The overall process is described by the following global equation:

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

carbon dioxide + water → glucose + oxygen

In the diagram, the equation is:

carbon dioxide + water + sunlight → glucose + oxygen

Answer:

The correct answer is A.

Explanation:

Y represents Glucose, a product of cellular respiration. Z represents Oxygen, which is also a product of cellular respiration.

(CO2 + Water + Sunlight = Glucose and Oxygen)

Given a template strand of 3'-atgcttggaca-5' and a partially-made complementary strand containing only 5'-tac-3', what would be the sequence of the new strand of dna (including the 5'-tac-3') if the only additional nucleotides available to dna polymerase were those containing the bases g, a, and c?

Answers

A complementary strand is complementary to the template strand when in the opposite direction, in this case 5'-3', the nucleotides that it contains are complementary to those of the template strand. Thus, the partially-made complementary strand 5'-TAC-3' will bind to the template strand starting on the 3'-ATG-5' portion. Then it is elongated by the DNA polymerase only up to the next nucleotide A, not included, because its complementary nucleotide is T which is not available. So, the sequence of the new strand on DNA would be 5'-TACGAACC-3'.

A nurse is evaluating the client's understanding of post cataract surgery instructions. the client needs further education when they state."i will report any yellow drainage to my provider"."i can return to my normal activities like cleaning my house and vacuuming.""i will report any nausea or vomiting"."my vision will improve over the next 4 to 6 weeks".

Answers

The answer to this question should be: "i can return to my normal activities like cleaning my house and vacuuming"

A post cataract surgery patient will be prone to an airborne allergen such as dust so it is not recommended to do any cleaning or be in a place with much dust. Vacuuming will increase the amount of the dust in the room and this might cause damage to the patient eye.

A nurse is evaluating the client's understanding of post cataract surgery instructions. The client needs further education when they state: I can return to my normal activities like cleaning my house and vacuuming.

Further Explanation:

The lens is that part of the eye which allows it to focus light or an image on the retina which is present at the back of the eye and is involved in converting light signal into nerve signal. Lens mainly consist of water and protein.

The cataract is the condition when there occurs clouding of the lens in the eyes which eventually affects the vision. This can affect either or both the eyes but cannot build out from one eye to another.

In normal vision, the proteins in the lens are present in a precise way which maintains the lens clear and allows the passage of light but with ageing, the protein may assemble together and start gathering to a small part of the lens which results in cataract.

Cataract surgery may increase the risk of retinal detachment.

There can be post-surgery effect of cataract treatment which may include itching, some fluid discharge, infection and mild discomfort.

Doctors may suggest the patients undergone cataract surgery to use some eye drops, wear an eye shield or eyeglasses and avoid bending from the waist and do the heavy household chores

compare the productivity of terrestrial and aquatic ecosystems against the percent of Earth’s surface area they occupy.

Answers

The 6 terrestrial ecosystems are tundra, taiga, temperate deciduous forest, tropical rain forest, grassland, and desert, these are distinguished from aquatic ecosystem by the limited supply of water. The two types of aquatic ecosystems are marine and freshwater.

Terrestrial productivity is more effective in the wet tropical climates as the net primary productivity decreases between equatorial and polar regions due to less sunlight and therefore there is a temperature decrease. Global productivity is limited by factors of water and sun, as most ecosystems rely on photosynthesis and water. Marine productivity tends to be higher, as rivers and water carry more nutrients and deposit them in other ecosystems. The most productive regions are areas such as wetlands and estuaries. i hope this helps!

Which of the following is most dense? asthenosphere, continental, crust , core , mantle, or oceanic crust

Answers

The mantle is the most dense (pretty sure at least)

The core is the most dense layer of the Earth, with a density between about 9.9 to 12.2 g/cm3, which is higher than the mantle, asthenosphere, and both the oceanic and continental crusts. Hence, option 4 is correct.

Among the options listed — asthenosphere, continental crust, core, mantle, and oceanic crust — the core of the Earth is the most dense. Specifically, the Earth's core is divided into the solid inner core and the liquid outer core with densities ranging from about 9.9 to 12.2 g/cm3 for the inner core and 9.9 to 12.2 g/cm3 for the outer core. In comparison, the mantle has a density of approximately 4.5 g/cm3, and even though the oceanic crust is denser than the continental crust, with a density of about 3.0-3.1 g/cm3 versus 2.7-2.8 g/cm3 for the continental crust, it is still less dense than the core. The asthenosphere, which is a part of the upper mantle, has a lower density than the mantle as a whole due to its semi-fluid nature and thus is also less dense than the core.

1. Step 1 The Sun emits energy. 
2. Step 2 Plants absorb energy from the Sun and use it for photosynthesis. 
3. Step 3 A rabbit eats the plants and uses the energy for growth and respiration. 
4. Step 4 A fox eats the rabbit and uses the energy for growth and respiration. 
5. Step 5 The fox dies and is decomposed. 

In an ecosystem, the energy flows from the producer to consumer levels. The plants utilise the energy from the sun and convert it into chemical energy. The chemical energy is stored as a form of energy molecules in the plants. The primary consumers eat the plants and get the chemical energy. The tertiary consumers eat the primary consumers and obtain energy from them. The dead organism is decomposed and the organic nutrients are restored in the soil.

Hence, the correct sequence would be:

1. The Sun emits energy. 

2. Plants absorb energy from the Sun and use it for photosynthesis. 

3. A rabbit eats the plants and uses the energy for growth and respiration. 

4. A fox eats the rabbit and uses the energy for growth and respiration. 

5. The fox dies and is decomposed.

One would expect to find this protein involved in the elongation of bacillus anthracis to form its typical shape

Answers

The protein involved in elongation of Bacillus Antrasis to form its typical shape is called FtsZ.
FtsZ is a GTpase that polymerises in nucleotide dependent manner head to tail to form a single stranded filaments that assemble into a contractible ring.
Final answer:

The protein involved in the elongation of Bacillus anthracis to form its typical shape is unknown. However, the shape of a protein is critical to its function.

Explanation:

The protein involved in the elongation of Bacillus anthracis to form its typical shape is unknown. However, the shape of a protein is critical to its function. For example, in the process of biological nitrogen fixation, the carrier protein leghemoglobin binds with a very high affinity to its substrate oxygen at a specific region of the protein where the shape and amino acid sequence are appropriate. If the shape or chemical environment of the active site is altered, the substrate may not be able to bind as strongly or not bind at all. Thus, for the protein to be fully active, it must have the appropriate shape for its function.

How are spores produced sexually differ from spores produced asexually?

Answers

The common example of a zygomycete is black bread mold (Rhizopus stolonifera), a member of the Mucorales. It spreads over the surface of bread and other food sources, sending hyphae inward to absorb nutrients. In its asexual phase it develops bulbous black sporangia at the tips of upright hyphae, each containing hundreds of haploid spores. If the mycelia of complementary mating types are present, the fungus reproduces sexually and produces zygosporangia. Zygosporangia are typically thick-walled, highly resilient to environmental hardships, and are metabolically inert. When conditions improve, however, they germinate to produce a sporangium or vegetative hyphae. 

Sexually produced spores in fungi are the result of genetic recombination between two different mating types, resulting in ascospores with diverse genetic material. Asexually produced spores, such as conidiospores, are genetically identical to the parent and form without the fusion of gametes.

Spores produced sexually and asexually in fungi have different origins and genetic compositions. Asexual reproduction frequently involves the production of conidiophores that release haploid conidiospores. These spores are genetically identical to the parent and are produced without the fusion of gametes.

In contrast, sexual reproduction involves the union of specialized hyphae from two mating types. The "male" strain produces an antheridium while the "female" strain develops an ascogonium. Fertilization occurs through plasmogamy, followed by karyogamy within the ascus, leading to the formation of ascospores. These spores contain genetic material from both parent strains and are produced following meiosis, which means they have a recombined genetic makeup. This difference in genetic composition between asexual and sexual spores can result in a greater genetic diversity in the latter, which can be beneficial for survival through unfavorable conditions.

The creature in the photograph is a protist, which is composed of only one cell. This means that a protist A) cannot reproduce. B) is a living organism. Eliminate C) cannot survive in water. D) gets energy directly from sunlight.

Protist can reproduce by dividing its cells. The organism also can survive in water. In fact, water was vital for the most organism and water depletion can cause the cell to die. The protist doesn't mean it gets energy directly from sunlight. It was a producer that can produce energy from sunlight.

B) is a living organism.

Explanation:

All living organisms must have 8 treats or characteristics to be called living things:

Most enzymes are proteins

Answer:

3. Proteins

Explanation:

Enzymes are naturally occurring groups of organic substances of protein origin (they can be form by 62 amino acid residues, such as 4-oxalocrotonate tautomerase enzyme monomer to 2500 residue size) with intra or extracellular activity that have catalyst functions. This is achieved by lowering the activation energy to allow a chemical reaction, resulting in an increased reaction speed and allowing the metabolism of living things. Importantly, although most enzymes are proteins, there are also enzymes consisting of RNA as ribozymes.

Why are reduction division and haploid gametes important?

Answers

Answer:

This is in order to maintain the species number of chromosomes.

Explanation:

Reduction division occurs by meiosis and it is very necessary in organisms that reproduce sexually.

Meiosis will take place in the ovary and testis to produce haploid gametes that have half the number of chromosomes compared to the parent cell .

During fertilization the two gametes will fuse to form the offspring an offspring with the same number of chromosomes as the parent. The species number of chromosome has been maintained.

Without meiosis or reduction division the off-springs would have double the chromosomes as the previous generation did.

tbe answer is protein.

Answer:

Keratin is a protein.

Explanation:

Keratin is a fibrous protein that has the characteristics of rigid conformation, elasticity and impermeability to water. It has animal origin and is found in the vertebrate epidermis and in some epidermal appendages, such as hair, nails, hooves, feathers and scales. This protein is produced in cells called keratinocytes, which are the most abundant in the human epidermis.

Like any protein, keratin is made up of amino acids. It has a large amount of cysteine residues, which is responsible for 7% to 20% of the total amino acids present in keratin. Note that cysteine is mainly located in the terminal region of the keratin chains.
