Answer:
C. those organisms that are best adapted to the environment will survive to produce more offspring
Explanation:
Natural selection is a key concept in the formulation of the theory proposed by Darwin in 1859. Natural selection is defined as the main force that drives the prevalence and the increase of advantageous phenotypic traits. Selection natural acts by differential survival and reproduction of individual organisms that have better adapted to the environmental conditions in which these organisms live. These organisms with a greater adaptive fitness have more chances to survive and reproduce, thereby transmitting (and perpetuating) their genes to the following generations.

C. 9
D. 38
The head makes up the largest percentage of body size __12___ weeks after fertilization.
What is fetal development of head?Fetus brain development is a complex process that continues throughout the pregnancy. At just six weeks, the embryo’s brain and nervous system begin to develop, although the complex parts of the brain continue to grow and develop through the end of pregnancy, with development ending around the age of 25.
At 11 weeks of pregnancy, baby’s head is about half the length of his body. Gradually, the body lengthens out and by about 28 weeks of pregnancy, baby’s body and head look a whole lot closer to normal.
Thus, the best option is B, i.e, 11 weeks among the given alternatives for the question.

What are evolutionary relationships?
Systematics, taxonomy, phylogenetics, and evolution are the four approaches used to investigate evolutionary connections. The branch of science known as systematics is concerned with classifying species and figuring out their relationships. It has two primary branches that may be separated:
Organisms are classified, given names, and grouped in taxonomy. A population, species, genus, or higher-level grouping like a family, order, class, phylum, kingdom, or domain can all be considered as a group or taxon. The word taxon is pluralized as taxa. The determination of evolutionary links or patterns of descent of species is via the study of phylogenetics.
The species of living things that exist now are all descendants of earlier ones. This is the result of evolution or merely time-related change. Branching evolutionary trees can be used to illustrate the evolutionary links between ancestors and their offspring. An evolutionary tree shows which ancestors gave rise to which descendants, much like your family tree does.
Therefore the correct option is B.

What is the genetic make-up of an organism?
Answer:
Explanation:
In a broad sense,genetic makeup of an organism can be regarded as the
"genotype" . It gives description about
complete set of genes an organism.
If we narrow it, it can be reffered to as "alleles" , this is is variant forms of a gene which is been carried by an organism. For instance, Humans can be regarded as diploid organisms, i.e there are two alleles at their each genetic position along with one allele which is been inherited from each parent. genotype of a specific gene is been represented by "Each pair of alleles". Instance of this is of "sweet pea plants" the gene responsible for flowering color posses two alleles, One of the alleles is responsible for coding purple flowers, symbolized with
uppercase letter F, the other allele is responsible for coding of white flowers
symbolized with Lowercase letter" f "
There are three possible genotypes which could be featured for Different population of a sweet pea, which are
✓FF
✓Ff
✓ ff.
Genotype of each plant have some contribution to the phenotype, by saying this, we mean outward appearance of its flowers.

The primary source of the specificity of enzymes is ________. The primary source of the specificity of enzymes is ________. their polarity, which matches that of their specific substrate their shape, which relates to the lock-and-key model their bonded transition metal, which is specific to the target substrate their delocalized electron cloud their locations within the cell
Answer:
their shape, which relates to the lock-and-key model
Explanation:
Enzymes are biological catalysts that are proteinous in nature. Their proteinous nature implies that they are made of amino acids, which forms a three-dimensional shape that accounts for their functionality and specificity. This means that enzymes are substrate-specific because of their 3D shape.
The three-dimensional shape of an enzyme determines the kind of substrate it will bind to. Enzymes, generally, catalyze reactions by binding to a substrate at their active site. This binding follows a lock and key pattern or model. In a nutshell, the primary source of specificity of enzymes is attributed to their SHAPE, which relates to the lock-and-key model.

Which consequence is a direct result of human population growth
Answer:
One of the largest environmental effects of human population growth is the problem of Global warming.
Economic development, urbanization, energy consumption, transportation/motorization due to rapid population growth are major driving forces of air pollution in large cities.
In order to support the growing population, forests are being destroyed at an alarming rate. Deforestation occurs when humans clear forests to use the land either for agriculture or for habitation. This leads to soil erosion and the extinction of plant species. Land animals also decline in numbers and even face extinction due to human expansion that encroaches on their natural habitat and limits their ability to spread geographically.
Humans also continue to put a great demand on the natural resources of our planet. Many non-renewable resources are being depleted due to the unrestrained use of fuel and energy. Many parts of the world also suffer from a shortage of food and water.
The growth of the population puts larger demands on our already limited resources. The environment on earth is suffering from the growth of the global population. The depletion of resources and biodiversity, the production of waste, and the destroying of natural habitat are serious problems.
Explanation:

as pollution.
Increase in human population has led to an increase in industries and
use of automobiles which emits different gases which are harmful. They

if two chromosome have equal length and size , and different in gene number would severity of chromosomal abnormalities in this two chromosome are equal?
Answer:
Unequal.
Explanation:
The severity of chromosomal abnormalities in these two chromosome are unequal that are equal in length and size but unequal in gene number are because the gene number are different from one another. If the size of gene increase or decrease from the normal range then it will leads to chromosomal abnormalities in the cell so the cells that has normal gene number has normal chromosome as compared to those cells where abnormal gene is present so the chromosomes are abnormal.

is called the
a. dominant trait.
b. recessive trait.
c first-generation trait.
d. second-generation trait.
Seed size in a plant is a polygenic characteristic. A grower crosses two pure-breeding varieties of the plant and measures seed size in the F1 progeny. She then backcrosses the F1 plants to one of the parental varieties and measures seed size in the backcross progeny. The grower finds that seed size in the backcross progeny has a higher variance that does seed size in the F1 progeny. Explain why the backcross progeny are more variable.
Answer:
The F1 progeny is completely heterozygous for the loci of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids
Explanation:
An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single locus, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing).
