Answer
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
Lamarck believed that the stretching elongated the giraffe's neck, which became a useful characteristic and was passed onto future generations. This resulted in the length of the giraffe's neck increasing over time. It is now commonly accepted that Lamarck's ideas were wrong.

In which squares should the phrase “Yellow pods” appear?
The given question is incomplete however the correct question and the flow chart is related to the question as follows:
The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. yellow pods are the dominant trait. The flowchart is missing the labels that describe the traits.
In which squares should the phrase “yellow pods” appear?
1. A and D
2.B and E
3. A, C, and D
4. A, B, C, D, and E
Answer:
The correct answer is: 3. A, C, and D
Explanation:
According to Mendel’s laws of inheritance, when a plant with the dominant trait is crossed with a plant with a recessive trait, as a result, the dominant phenotype appears in all the F1 offspring. On Self cross F1 offspring, produces F2 offspring with dominant and recessive traits.
In the given scenario, pea plant with ‘yellow pods’ are dominant and pea plant with ‘green pods’ is recessive.
Therefore, when pea plant with yellow pods is crossed with the pea plant with the green pod, the F1 offspring (C) produced are with yellow pods.
Thus, parent (A) is with yellow pods and F2 offspring (D) is with yellow pods.

How many chemical bonds can each carbon atom form?
Answer:
It has four valence electrons, which it can achieve a full outer energy level which forms four covalent bonds. When its bonds only with hydrogen, it forms compounds which is called hydrocarbons. Carbon can be form in single, double, or triple covalent bonds with other carbon atoms.
Explanation:
The valency of carbon is four. Therefore, carbon can form four chemical bonds.
What is a chemical bond?It is the attraction between two atoms, they share or exchange electrons to form molecules or compounds is known as a chemical bond. They share electrons to fulfill their valency. The number of bonds depends on the number of valencies.
There are three types of bonds and that are covalent, ionic, and metallic bond. A covalent bond or molecular bond is formed by sharing of electrons, it occurs in non-metals. Ionic bonds are formed by exchanging electrons, it occurs in both metal and non-metal. metallic bonds are present between two metals. The covalent bond is the strongest bond.
There are four valencies in carbon. Therefore, it can make four bonds.

A red blood cell placed in distilled water will swell and burst due to the movement of Your answer: salt from the distilled water diffusing into the cell water molecules moving by osmosis into the cell water from the red blood cell moving into the distilled water
Answer:
Due to the movement of surounding water ijnto the cell.
Explanation:
A red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.
Osmosis is the movement of water that diffuses from a higher water concentration area to a lower water concentration area.
The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic to the red blood cell.The red blood cell will gain water, swell ad then burst.Thus, a red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.

Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the choices provided A B C D
Answer:
A. 14.59
Explanation:
Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.
Next, we have to know that to round a number;
* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.
* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit
Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant
Hence, 14.587020 will be:
= 14.587020
= 14.58700
= 14.59000
We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right
Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59
Answer:
a.14.59

The populations living on a rough, steep mountain would have a higher rate of
speciation than those living in a large, open grassland because the mountain
would
A. show less habitat fragmentation
B. provide its populations with more resources
C. isolate populations into subgroups
D. have fewer niches for organisms
Answer:
The correct answer is option C, that is, have a wider range of environments.
Explanation:
It has been known that geographic isolation is a general way for the initiation of the process of speciation, like the rise of mountains, rivers changing course, migration of organisms, continental drift, due to this what was once a steady population gets differentiated into two or more kinds of smaller populations.
A mountain range, due to distinctions in temperature and precipitation as a result of different altitudes, can lead to a higher rate of speciation. Due to these differences, a single mountain range can exhibit an enormous array of biodiversity and climate zones.
In comparison to populations living in broad, open grasslands, populations living on rocky, steep mountains would experience a higher rate of speciation due to the mountain's ability to divide populations into smaller subgroups . So, the correct option is C.
How the population have higher rate of speciation?Geographic isolation is known to be a common way for the beginning of the process of speciation, similar to the formation of mountains, the alteration of rivers, the migration of organisms, and continental drift. As a result, what was once a stable population becomes divided into two or more different kinds of smaller populations.
A mountain range might result in a greater amount of speciation because to differences in precipitation and temperature as a result of various altitudes. A single mountain chain can display a huge variety of biodiversity and temperature zones as a result of these variances.
Therefore, the correct option is C.

C. Jessica inherited one recessive form of the

Jessica inherited one dominant form of the
gene from each parent.
Answer:
D
Explanation:
Dominant and the recessive allele are the traits present in the genes that get inherited from the parent to their offspring.
The trait that is visible in the phenotype is called dominant while the trait that gets masked in the proximity of the dominant allele is called recessive.
The correct answer is:
Option C. Jessica inherited one recessive form of the gene from each parent.
This can be explained by :
The genotype of Jessica's eyes = bb (light)The genotype of her parents = Bb (dark eyes)See the attached image below for the cross:
