Answer:
Cell serves as the basic building blocks for building the structure or the body of the living organisms. Now, certain type or specific number of cells come closer and arrange themselves in such a sequence that they need to perform a unique or specific task by making up a whole organ structure.
Explanation:
There are certain cells inside the human body which makes up a single organ and then performs the whole function specifically by themselves, as we have the "myocardial myocytes". These are the specific type of cells which are required for the heart's cardiac muscles to develop or grow in a given pattern. As these cells are specialized for making up or building up of the cardiac muscles which in turns results in the heart structure. And performs the basic function of supply of blood and the required materials i.e nutrients to the different cells and organs.
B. the Sun appears lower in the sky than during other seasons.
D. the Sun rises in the Northeast and sets in the Northwest.
On the northern hemisphere the north is to the left, the Sun rises in the east (far arrow), culminates in the south (to the right) while moving to the right and sets in the west (near arrow). Both rise and set positions are displaced towards the north in summer, and towards the south for the winter track.

Answer:
its b
Explanation:
because days get shorter in the winter
B. Earth's tilt on its axis would decrease
C. Earth's climate would become warmer
D. length of days and nights would increase
Which of these would most likely happen if there is a sudden increase in the number of sunspots?
C. Earth's climate would become warmer
The correct answer is option C.
The sudden increase in sunspots will make the Earth more warmer because the more the sunspots, more energy is delivered to the atmosphere. This increases the global temperatures of the Earth.
Answer:
The correct answer is C.
Explanation:
Sunspots increase and decrease through an average cycle of eleven years.
There is a debate of how much this sunspot would affect the earth`s temperature, the earth`s climate is sensitive to very weak changes in the Sun`s energy. During maximum sunspot activity, there`s a very slight increase in the energy output of the sun. Ultraviolet radiation increases during high sunspot activity, and this can have a large effect on Earth`s atmosphere.

Pedigree charts are used to trace the passing out of traits(characteristics) through generations.
In the given pedigree of 5 generations, the pattern of inheritance of genetic abnormality of polydactyly(extra fingers in hands and toes) is studied . The types of pattern of inheritance in traits over generations.
(a) Genotype of the parents for the trait Polydactyly in generation 1
Since each parent provide one allele of each trait to the offspring there are dominant and recessive genes on the basis of the expression of the character or trait. The genotype of the parents for thre trait of polydactyly in generation 1 is Recessive. Because both the parents do not have the abnormality and their offspring shows(expresses) the trait.
(b) In humans there are 46 chromosomes arranged as 23 sets of 2 chromosomes in a cell which is described as (2n). These somatic cells undergo Mitotic division to produce 2 identical daughter cell with 2n chromosomes and they are called diploid cells. When Meiosis takes place one cell is divide into 4 Haploid cells with 23 chromosomes each, ie, the single set of chromosomes represented by n. These Haploid cells are the gamates which transfer the genetic information from parents to offspring. The gamates are 2 types the sperm and egg cells , both are haploid and during fertilization a sperm cell fuses with eggcell to form a zygote with 2n (46) chromosomes.

Explanation:
For the recessive trait to be expressed, both parents should have at least 1 allele for the recessive trait. Now you can see that both recessive traits were expressed in at least one of the off-springs, this means that both parents had the allele for each recessive trait.
