Which of the following statements is an important consequence of the first law of thermodynamics for a living organism? The ener

gy content of an organism is constant. Organisms grow by converting energy into organic matter. An organism ultimately must obtain all of the necessary energy for life from its environment. The entropy of an organism decreases with time as the organism grows in complexity.

Answer:

An organism ultimately must obtain all of the necessary energy for life from its environment.

Explanation:

The First Law of Thermodynamics is also known as the law of conservation of energy. This law states that energy can neither be created nor destroyed, it only can change its form. The energy in a closed system remains constant.

All the organisms require energy to perform their life processes. The ultimate source of energy is the sun.  The energy is supplied by the sun is used by green plants to synthesise food (glucose), chemical energy. Thus, light energy is converted to chemical energy. The chemical energy is transferred to animals through food chains.

Alkaptonuria is an infrequent autosomal recessive condition. It is first noticed in newborns when the urine in their diapers tur
Arisa [49]

Answer:

See the answer below

Explanation:

Let the disorder be represented by the allele a.

Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.

Since the four adults are carriers, their genotypes would be Aa.

                    Aa     x     Aa

Progeny:    AA    2Aa    aa

Probability of being affected = 1/4

Probability of being a carrier = 1/2

Probability of not being affected = 3/4

(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2

(b) The chance that  the third child of Sara and James will be free of the condition = 3/4

(c)

(d) If someone has no family history of the disorder, their genotype would be AA.

                 AA     x     aa

                        4 Aa

<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0

(e)

(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0

Appositional growth occurs within the ____________ . In this process, ____________ in the inner cellular layer of the periosteum
BaLLatris [955]

Answer:

Appositional growth occurs within the periosteum . In this process, osteoblasts in the inner cellular layer of the periosteum produce and deposit bone matrix within layers parallel to the surface, called external circumferential lamellae. These lamellae are analogous to tree rings: As they increase in number, the structure increases in diameter. Thus, the bone becomes wider as new bone is laid down at its periphery. As this new bone is being laid down, osteoclasts along the medullary cavity resorb bone matrix, creating an expanding space.

Explanation:

The blanks shown in the question above were filled with the correct term for each situation, thus creating a message with veracity and with the right concepts, creating an efficient, explanatory and direct message, showing exactly what happens in the situations shown in the question. In addition, the blanks were filled with the correct grammar and the necessary punctuation to make the text cohesive.

A germ cell and zygote represents the biological level of organization. __________
kompoz [17]

Answer: Cell

Explanation:

The cell is the structural and functional unit of life. It is the the most basic level. A life starts from a single cell.

When a male and female gamete(germ cell) fuse together they form zygote. Firstly it is a single cell surviving inside the mother's womb.

Then differentiation takes place and the cell keeps on dividing to form different tissue layers and then organs form which makes a complete baby. Hence, zygote and germ cell are cellular level of organization.

The half-life of protactinium-226 is 2 minutes if you started with 20 grams of pa-226 how much do you have after 8 minutes
Hunter-Best [27]

Divide the amount in half for every 2 minutes

0 minutes = 20 grams

2 minutes = 20/2 = 10

4 minutes = 10/2 = 5

6 minutes = 5/2 = 2.5

8  minutes = 2.5/2 = 1.25 grams

In a biological membrane, the phospholipids are arranged with the fatty acid chains facing the interior of the membrane. as a re
nlexa [21]
Because the fatty acid chains are saturated and unsaturated hydrocarbons, it implies that the fatty acid chains of a phospholipid is not attracted to water hence why they are turned inwards towards each other and away from aqueous medium.  This implies that the interior of the membrane is HYDROPHOBIC (water-fearing/water-repelling).
