describe the life cycle of a bean beetle​

Answers

Answer:

The larvae of this species feed and develop exclusively on the seed of legumes (Fabaceae) hence the name bean beetle. The adults do not require food or water and spend their limited lifespan (1–2 weeks) mating and laying eggs on beans. ... Pupation is the complete metamorphosis of the larval maggot to a winged adult.

Explanation:

hope it's helpful

Pupation is the complete metamorphosis of the larval maggot to a winged adult. The adult that results from pupation chews through the seed coat and emerges from the bean. ... The elapsed time from newly laid eggs to the emergence of adult beetles varies between bean beetle strains and environmental conditions.

Why do you think leaves have stomata on their underside only? Explain.

Answers

The stomata must be open during the daylight hours to let oxygen and carbon dioxide pass through. While they are open, water vapor escapes into the atmosphere (transpiration). ... Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water.

In a lotus plant, stomata is found on the upper epidermis of the leaf.

Stomata are responsible for the exchange of gas with the surrounding atmosphere of the leaf. Their guard cells stay taut during the day to keep the stoma open.

Guard cells can only stay open if they are saturated with a certain quantity of water.

From this information we can infer that stomata are typically found on the lower epidermis to prevent water damage when it rains.

The rain would not only cover the openings, it would also ruin the osmotic balance of the guard cells causing inefficiency and damage to the cycle of gaseous exchange.

Natural selection probably selected against such plants giving rise to those with stomata on the underside.

Un instructor desea preparar un experimento sobre movimiento armónico simple. Sólo dispone de una masa de 2 kg pero tiene una colección de resortes. ¿Qué constante elástica, en N/m, debe elegir para tener un período de 2 s?

Answers

Answer:

Constante de resorte, k = 19.745 N/m

Explanation:

Dados los siguientes datos;

Masa, m = 2 kg

Periodo, T = 2 segundos

Para encontrar la constante del resorte, k;

[tex] Period, \; T = 2 \pi \sqrt {\frac {m}{k}} [/tex]

Dónde;

T es el período. m es la masa del objeto. k es la constante del resorte.

Haciendo k el tema de la fórmula, tenemos;

[tex] k = \frac {(2 \pi )^{2}m}{T^{2}} [/tex]

Sustituyendo en la fórmula, tenemos;

[tex] k = \frac {(2 * 3.142)^{2} * 2}{2^{2}} [/tex]

[tex] k = \frac {6.284^{2} * 2}{4} [/tex]

[tex] k = \frac {39.49 * 2}{4} [/tex]

Applying Concepts Your friend is playing a song on a piano. Whenever your friend hits a certain key, the lamp on top of the piano rattles. Explain why the lamp rattles.

Answers

Answer:

The lamp rattles because close resonant frequency.

Explanation:

The phenomenon of increased amplitude is known as resonance when the frequency of a periodically applied force is equal to or close to the natural frequency of the system it affects. When a resonant frequency oscillating force is applied to a dynamic system, the system oscillates with greater amplitude than when the same force is applied at non-resonant frequencies.

Resonant frequencies or resonance frequencies of the system are frequencies when the response amplitude is at a relative maximum. Due to the storage of vibrational energy, small periodic stresses at a resonance frequency of the system can cause significant amplitude oscillations in the system.

Thereforee, the lamp rattles because close resonant frequency.

A __________ is an example of a signal molecule that can bind to an intracellular receptor and thereby cause a gene to be turned on or off. a protein b glyceride c nucleic acid d steroid e carbohydrate

Answers

Answer:

D. steroid

Explanation:

Intracellular receptors are a type of receptors located inside the cell, specifically in the cytoplasm or nucleus. When intracellular receptors are activated by ligands called SIGNALLING MOLECULES, they change shape and regulate genetic expression in the nucleus i.e. they induce turning on and off in a gene.

However, signalling molecules that activate intracellular receptors are usually hydrophobic hormones because they need to easily diffuse through the cell membrane and bind to the receptors located internally. Example of these hydrophobic signal molecules are STEROIDS.

"Draw a pedigree for hitchhiker’s thumb. Your pedigree should cover at least two generations and include both dominant and recessive forms of the trait. Label the pedigree with genotypes, using the letter H to represent the dominant allele for the trait and the letter h to represent the recessive allele."


I'm confused on the part about having two generations. How do I set up the pedigree?

Answers

Answer and Explanation:

First, you need to know how to interpret a pedigree representation.

Family members

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

Trait/Phenotype

→ Healthy/normal/not affected  individuals are represented with empty figures

→ Affected/mutated individuals are represented with solid black figures

Generations

→ Each file is represented with a roman number, indicating the Generation.

 

Now, what we need to do is to draw a pedigree for a hitchhiker’s thumb. We know that this is an autosomal dominant trait, which we will represent with an H. No hitchhiker's thumb is the recessive trait, and it will be represented with an h.

Our pedigree should cover at least two generations and include both dominant and recessive forms of the trait.    

We can cross two heterozygous individuals, Hh, who are the first generation in our pedigree. This cross will result in a woman and a man with No hitchhiker's thumb, another man with a hitchhiker's thumb, HH, and another woman with a hitchhiker's thumb, Hh. These individuals will represent the second generation in the pedigree. Finally, we can cross the man with No hitchhiker's thumb, hh, with a woman who does not have a hitchhiker's thumb either, hh. And the woman with a hitchhiker's thumb, Hh, with a man with a hitchhiker's thumb, HH. The result of these crosses will be the third generation.

The representation would be like following,

I → First-generation: First cross

Man Hh (1)  Woman Hh (2)

II → Second-Generation: F1 and second crosses

Man hh (3)  x    Woman hh (4)Woman hh (5)Man HH (6)Woman Hh  (7) x   Man HH (8)

III → Third-Generation:

A boy (9) and a girl (10) hhA girl (11) HH

You will find this pedigree in the attached files. In this example, we included three generations. The first one belongs to the grandparents, the second one to parents, aunts/uncles, and the third one to grandchildren.  

If you draw another pedigree, remember to include

the figures representing males and females, color and H/h representing the phenotype, Roman numbers representing the generations, and optional, numbers naming each member.

Capillaries b) Thin-walled blood vessels that are less elastic than arteries c) Thick-walled, muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles d) Small arteries that deliver blood to capillaries e) Small vessels that connect the capillaries to the veins

Answers

Answer:

Arterioles - D

Arteries - C

Veins - B

Capillaries - A

Venules - E

Explanation:

This question is describing the blood vessels that make up the circulatory system. The blood vessels with their accurate description are as follows:

- ARTERIES: Arteries are the most elastic and thick-walled blood vessels that functions to carry blood away from the heart using great pressure. Arteries are muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles.

- VEINS: Veins are blood vessels that carry deoxygenated blood back to the heart. Veins have a thin wall and are less elastic in comparison with arteries.

- CAPILLARIES: Capillaries are smallest blood vessels designated to connect the smaller arteries or arterioles to venules. They are also thin-walled.

- ARTERIOLES: Arterioles are small arteries or branches of an artery that connects the arteries to capillaries. Arterioles deliver blood to capillaries.

- VENULES: Venules are tiny veins or branches of a vein that connects the veins to the capillaries. Venules deliver blood from capillaries to veins.
