Answer:

Brain size increase due to find out improved quality diets whereas cecum size decrease due to reduction of its need.

Explanation:

Brain size increased due to the need to increase the mental capacity of an organism in order to explore the environment for the survival such as search for improved quality diet and the cecum size decreased because omnivorous diet improved due to the reduction of its need as a component of the digestive system. Insects have different respiration system as compared to vertebrates because vertebrates uses lungs for respiration whereas the insects uses tracheal tubes for the absorption of oxygen and removal of carbondioxide gas.

Answer:

different assessments of environmental factors

Explanation:

In humans, for predicting the future phenotype of any individual, the PSR is used.

A trait may be defined as the state of a character that is a distinct variation of the phenotypic characteristic of any organism.

The following factors contributes to the differences in the complex trait risk predictions in the different laboratories :

-- differing methods of the combining risk from the multiple genetic variants.

-- genotyping of the different variants.

-- selection of the different genetic variants for such risk determination.

Thus the factor which does not contribute is :

"different assessments of the environmental factors."

Answer:

14. (a) Pb

15. (d) Al

16. (A) increases

Explanation:

14.

In the reactivity series of metals an element can displace another element from a compound if and only if it is not placed below that metal, as the reactivity of metals decreases when moving from top to bottom- if a metal is placed below Hydrogen it means that it is less reactive than Hydrogen and hence cannot displace Hydrogen from its compound.

All options except A are placed below Hydrogen in the reactivity series, so they wont displace Hydrogen from its compound, but option (a) that is Pb can do so as it is above Hydrogen in the reactivity series.

15.

Al is placed below Mg in the reactivity series and hence cannot displace Mg from its compound.

16.

The reactivity of metals increases down the GROUP.

[CAUTION :- We were talking 'bout REACTIVITY SERIES in the top 2 questions where reactivity decreases down the group, but we're talkin' 'bout GROUPS of the periodic table here, where reactivity increases down the group.]

The size of metals increases down the group causing their valence electrons to drift far from the nucleus so that they can be lost easily. The metals have a property of losing electrons so the more electrons it can lose more will be its reactivity.

Hence, reactivity increases down the group.

Answer:

clone

Explanation:

C. Growth hormone promotes the closure of the epiphyseal plate.

The closure of the epiphyseal plate is NOT an effect of growth hormone (option c).

The epiphyseal plate is a layer of hyaline cartilage between the epiphyses and metaphyses at the ends of long bones.

The epiphyseal plate is completely closed when bone growth is completed (around age 18 to 21 years).

Different hormones (i.e., testosterone and estrogen) released at puberty initiate the closure of epiphyseal plates.

In conclusion, the closure of the epiphyseal plate is NOT an effect of growth hormone (option c).

Answer:

the answer I got for the question you asked is 75%

Answer:

623 monomers

Explanation:

In a dehydration synthesis reaction, one water molecule is removed for every bond that is created between 2 monomers.

Linking 3 monomers together would remove 2 water molecules.

Following this pattern, the number of water molecules removed will always be one less than the number of monomers that were joined together.

So, if 622 water molecules were removed, then 623 monomers were joined together.

The answer is 623 monomers.

Answer:

Regulation of cell processes

Explanation:

Lactase is an enzyme that helps in the breaking down of disaccharide sugar, lactose, found in many foods. It does it by converting the lactose into its component reducing sugars - glucose and galactose. This enzyme is produced by some special cells lining the intestinal walls of humans and forms a kind of chemical barrier known as brush border where foods must pass through before being absorbed. By so doing, foods are screened for the presence of lactose and any lactose is broken down before the foods are given a pass.

Answer to 6:

The probability of two offspring with the same genotype is very low because due to recombination between the chromosomes of the father and mother each gamete has a different composition of genetic material. The only chance that they share the genotype is if they were zygotical twins.

Answer to question 7:

When you increase the number of chromosomes the variability will increase too.

Answer:

trans

Explanation:

From the given information:

The study observes the genes present in mice for eye color and tail length. Since both genes are linked, it implies that they exist in the same chromosomes.

Black eyes is dominant over apricot eyes

Let Black eye be B and apricot eyes be b

Long tail is dominant over short tail

Let long tail be L and short tail be l

If double heterozygote(homoozygous-recessive) engage in the testcross

Then:

From the result given:

The parental combinations are:

Apricot eyes, Longtail  (bL / bl) =  33

Black eyes, Short tails (Bl / bl) = 30

The recombinant genes are:

Black eyes, Long tails (BL / bl) =  17

Apricot eyes, Short tails (bl / bl) = 20

The recombination frequency relates to the distance between the two genes which can be computed as:

= (20+17)/100

= 37%

Thus; the heterozygous parent is in trans arrangement.

Two different ways that you could classify the following  items: banana, lemon, sandwich, milk, orange, meatball, and salad, are the following:

Fruits and not fruits, where the fruits would be banana, lemon and orange; and the non-fruits would be sandwich, milk, meatball and salad.

Food of animal and vegan origin, where the food of animal origin is sandwich, milk and meatball, and the vegan food is banana, lemon, orange and salad.

The following food items can be classified based on either plant or animal origins.

Food is a substance that contains nutrients that is required for the growth and maintenance of the living organisms.

Food can be gotten from various sources which includes plant and animal sources.

Examples of plant sources are banana, lemon, sandwich, orange and salad

Examples of animal sources are milk and meatball. This is because it can be processed from cow and ram.

Therefore, the following food items can be classified based on either plant or animal origins.

Answer:

A nuclear reactor is driven by the splitting of atoms, a process called fission, where a particle (a 'neutron') is fired at an atom, which then fissions into two smaller atoms and some additional neutrons. ... The fissioning of atoms in the chain reaction also releases a large amount of energy as heat.

C. The cork in bulletin boards

Explanation:

Cork is made primarily from a plant called Quercus suber (the cork oak).

Answer:

Take two potted plants and provide equal conditions to both.

Explanation:

Two potted plants i.e. one is placed near the nuclear accident site while on the other hand, the other is placed far away from the nuclear accident. Provide equal conditions to both plants so that we can find out the hypothesis that  the frequency of mutations decreases with the organisms distance from the source of radiation. The result shows that the potted plant that is located near to the nuclear accident site having high frequency of mutation as compared to other plant due to the radiation present at that location.

d. Ziehl - Neelsen's staining

Explanation:

The mycobacteria is stained with the Ziehl - Neelsen's staining. Hence, option (d) is the correct answer.

Answer:

a. Her mother has zig-zag antennae.

b. Her brother has zig-zag antennae.

Explanation:

Available data:

Maternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. Even though the progeny has a different genotype, it is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. The maternal effect is commonly seen in insects and might be seen in some mammals and plants.

So, if a female has zig-zag coils, this means that the mother also has zig-zag antennae and that all the brothers and sisters of this female ant have zig-zag antennae, independently of their genotype.

a. Her mother has zig-zag antennae ⇒ True. The trait is inherited from the mother.  

b. Her brother has zig-zag antennae ⇒ True. The whole progeny will express sig-zag antennae.

c. This female carries the zig-zag allele ⇒ Not necessarily.

d. This female's offspring will have zig-zag antennae ⇒ Depends on it´s genotype

Answer:

Phenotypic approach for bacterial identification

Explanation:

Bacterial identification can be done by conventional methods, which are based on phenotypical characteristics. These methods are much affordable and reasonable.

Phenotypical identification is based on bacteria´s observable characteristics, such as their morphology, development, and biochemical/metabolic properties.

It is important to consider that these methods do not provide absolute certainty. They can only indicate the genera or species to which the bacteria under study may belong.

Some primary evidence is usually used for fast bacteria identification:

Knowing that the bacteria in the exposed example was isolated and grown in culture, then Gram-stained and tested for biochemical reaction, we can assume that the approach for its identification is phenotypic.
