Answer: pls see the attached image {hope it makes sense}

The statement that, the purpose of a flower is sexual reproduction. Only flowering plants can bear fruits, which contain the seeds. The fruit's purpose is to protect and disperse the seeds, is True.

Flowers are the reproductive structures of flowering plants and play a crucial role in sexual reproduction. They produce both male and female gametes (pollen and eggs, respectively), which are required for fertilization to occur. Fertilization leads to the development of seeds, which are contained within the fruit.

The fruit not only protects and nourishes the seeds, but it also helps to disperse the seeds, increasing the chances of survival and colonization of new areas. The fruit's size, shape, and texture are adapted to attract animals, such as birds and mammals, that will eat the fruit and disperse the seeds in their droppings.

Answer:

Traits acquired during an organism's lifetime cannot be passed

Explanation:

The law of use and disuse of organs as postulated by Jean Lamarck was wrong due to the fact that environmentally acquired characters cannot be passed to offspring.

Changes to organisms that are not the level of the gene cannot be passed to the offspring. For example, a wrestler that got big muscles due to constant work out cannot pass big muscles to his offspring. The offspring will need to work out in order to have big muscles. This is because big muscles in the wrestler is environmentally acquired.

Only changes that happen to the genome of an organism (mutation) can be passed to offspring.

Answer:

rho

Explanation:

The Rho factor is a prokaryotic helicase protein that acts in bacteria to mediate the process of termination of transcription. In Escherichia coli, the Rho factor is a hexameric ring-shaped helicase and each subunit of this factor contains two domains involved in RNA binding and ATP hydrolysis. The Rho factor binds to the transcription terminator site on single-stranded RNA and then continues along the messenger RNA (mRNA) strand until it reaches the RNA polymerase, subsequently triggering its dissociation from the DNA and thus the termination of transcription.

Helicoid cholesteric is the name for a nematic phase with helical twist.

The nematic phase is characterized by the correlation of long molecular axes due to the one-dimensional orientation order of the molecules, but the orientation order is not polar. There is no translation order within the nematic phase.

Helicoid cholesteric phases are similar to nematic phases in that they exhibit long-range orientational order at the positions of the molecular centers of mass and no long-range order.

An iron cube has sides that measure 0. 5 meter. The cube is cooled from 95°C to 75°C. the change in volume of the iron cube is -9 × 10⁻⁵ m³.

The change in volume of the iron cube can be calculated using the formula: ΔV = 3αV₀ΔT, where ΔV is the change in volume, α is the coefficient of linear expansion, V₀ is the initial volume, and ΔT is the change in temperature.
Given:
α = 12 × 10⁻⁶ °C⁻¹ (coefficient of linear expansion for iron)
V₀ = 0.5³ = 0.125 m³ (initial volume of the cube)
ΔT = 75 - 95 = -20°C (change in temperature)
Plugging in the values into the formula:
ΔV = 3αV₀ΔT
ΔV = 3 × 12 × 10⁻⁶ °C⁻¹ × 0.125 m³ × (-20°C)

There are different ways or methods of protecting crops from pest and disease infestation. Two of those ways as mentioned in this question are the chemical control and biological control. Biological control of crop protection involves the use of natural enemies of crop pests, which happens to be living or biotic organisms while chemical control entails the use of pesticides and herbicides to control crop pests and diseases.

Among these two methods, the chemical control is more effective because it yields instantaneous results and gets rid of pests and diseases faster. However, in terms of sustainability, the biological control method is more eco-friendly. Hence, based on this question, biological is not more effective than chemical control of crop protection.

The claim made in the readings that jade plants have properties that allow them to survive long dry spells can be supported by several reasons and evidence from the texts.

Firstly, jade plants belong to the succulent family. Succulents are a group of plants that have adapted to survive in arid environments with little water availability. They store water in their leaves, stems, or roots, allowing them to withstand long periods without rainfall. This ability to store water is a key adaptation that enables succulents, including jade plants, to survive in dry spells.

Additionally, the text may provide evidence of specific characteristics of jade plants that contribute to their ability to survive in drought conditions. For example, the text may mention that jade plants have thick, fleshy leaves that can store water. These leaves have a waxy coating that helps reduce water loss through evaporation. This adaptation allows jade plants to retain moisture for extended periods, even in dry conditions.

Furthermore, jade plants often have shallow root systems that spread out horizontally rather than deeply into the soil. This helps them capture any available rainfall quickly and efficiently. The shallow roots also allow them to absorb moisture from the air when it is present, further supporting their survival during dry spells.

Considering what we may already know about succulents, we can further support the claim. Succulents, including jade plants, have evolved to survive in harsh, arid environments where water is scarce. Their ability to store water in their tissues and their efficient water-use strategies make them well-equipped to withstand prolonged dry spells.

In summary, jade plants possess several characteristics that allow them to survive long dry spells. These include their succulent nature, which enables water storage in their leaves, stems, or roots, as well as their ability to reduce water loss through waxy leaf coatings. Their shallow root systems and efficient water-use strategies also contribute to their survival during drought conditions.

a. True

b. True

c. False

d. True

e. True

The correct statements are:

a. Each gene in an individual consists of two alleles: one comes from the mother and one from the father. This is true because an individual inherits one allele for each gene from each parent.

b. Some alleles are recessive, meaning they ultimately determine the expression of a trait if they are present. This is true because a recessive allele only determines the expression of a trait if it is present in two copies of the genotype.

c. Other alleles are dominant and are much less likely to be expressed. They are only seen if two copies are found in the genotype. This is false. Dominant alleles are more likely to be expressed and are seen if there is at least one copy of the allele in the genotype.

d. During meiosis, each allele segregates and produces gametes that have only one allele for each gene. This is true because during meiosis, each allele separates, and only one allele goes into each gamete.

e. During fertilization, a new individual is produced with two factors for each trait, one inherited from the mother and the other from the father. This is true because each parent contributes one allele for each gene, and the offspring inherit one allele from each parent for each gene.

In a cell respiration lab that investigates the rate of fermentation in yeast, the rate of fermentation can be measured by monitoring the production of carbon dioxide gas.

During fermentation, yeast cells produce carbon dioxide as a byproduct, which can be measured using a gas collection system. A common method is to set up a fermentation tube or gas collection tube filled with a sugar solution and yeast, and attach a gas collection system to the tube.

As the yeast cells ferment the sugar, carbon dioxide gas is produced and collected in the gas collection system. The rate of fermentation can be calculated by measuring the volume of gas produced over a set period of time and dividing by the time interval.

Alternatively, the rate of fermentation can be measured indirectly by monitoring the change in pH of the solution as the yeast cells consume the sugar and produce acidic byproducts. This can be measured using a pH indicator or pH meter.

A buoy floating in water will move only horizontally and when caught in a wave floats vertically in water.

The buoyancy of an object determines whether it will float or sink. An object's propensity to float on or rise in a liquid is known as buoyancy. A thing is considered to be positively buoyant if it floats in water. A sinking item is negatively buoyant. Keep your chest filled with air at all times, and only take shallow breaths.

The easiest way to float is horizontally, either on your front or back. To maintain buoyancy, it again helps to keep your lungs inflated. Because surface waves propagate along a medium's surface, the body moves vertically. In a general circular motion, the particles of a medium move up and down as well as back and forth.
