can someone please help me with this !

Answer:

Below

Explanation:

The reason why we can conclude that all species have common ancerstory is that all the species have several same base pairs. Here are a few listed:

A-G-G-C

As well as this later on:

C-C-A-A-C-C

Because this strand of DNA has several common base pairs, we can conldude that the species have common ancestory that made it this way.

Hope this helps!

Answer: Realized Niche

Explanation:

Realized niche is also referred to as Post Competitive niche and can be defined as a thriving environmental area created by a group of organisms to survive from an exsisting Faundermental  niche where interactions (predation, competition, light, water,food) with other organisms were limited and competed for.  

For example. In a tree( Faundermental niche) which houses different species of birds, In order to survive, each specie of the birds will create a realized niche so as to survive from predation, competition, light etc which the whole tree provides.

Answer:

Root hair cells (black arrow pointing at one of the root hair cells) are single tubular root cells. Their distinctive lateral elongation increases the surface of exchange between the plant's root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere.

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.

Smooth muscle fibers have an oblong shape, much like a football. They’re also thousands of times shorter than skeletal muscle fibers. Similar to skeletal muscles, cardiac muscles are striated. They’re only found in the heart. Cardiac muscle fibers have some unique features.

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.

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.

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;

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]

[tex] k = \frac {78.98}{4} [/tex]

Constante de resorte, k = 19.745 N/m

Answer:

La mitad de cromosomas.

Explicación:

Las células haploides se refieren a aquellas células que tienen la mitad de cromosomas. Estas células haploides se forman debido a la división celular de la meiosis. En la división celular de la meiosis, una célula madre se divide en cuatro células hijas que tienen la mitad de cromosomas. Estas células haploides están presentes en los espermatozoides de los gametos masculinos y femeninos, que se fusionaron formando células diploides que tienen el doble de cromosomas. El cigoto formado debido a la fusión de espermatozoides y óvulos son de naturaleza diploide.

Answer and Explanation:

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

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

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

→ Affected/mutated individuals are represented with solid black figures

→ 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.    

The representation would be like following,

I → First-generation: First cross

II → Second-Generation: F1 and second crosses

III → Third-Generation:

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
