3:They move with the help of finger like projection called pseudopodia.

4: Cytoplasm is differentiate into two parts, outer portion is ectoplast and inner portion is called endoplast.

5.Amoebae are eukaryotes whose bodies most often consist of a single cell.

6. The cells of amoebae, like those of other eukaryotes, possess certain characteristic features.

7.Their cytoplasm and cellular contents are enclosed within a cell membrane.

8.Their DNA is packaged into a central cellular compartment called the nucleus..

Each amoeba contains a small mass of jellylike cytoplasm, which is differentiated into a thin outer plasma membrane, a layer of stiff, clear ectoplasm just within the plasma membrane, and a central granular endoplasm.

9. The endoplasm contains food vacuoles, a granular nucleus, and a clear contractile vacuole..

10.People usually become infected from warm freshwater lakes and rivers..

CBSE > Class 10 > Social Science

1 answers

Priya ✧*｡٩(๑˙╰╯˙๑)و✧*｡ 5 years, 3 months ago

The idea of power sharing has emerged in opposition to the notions of undivided political power. For a long time, it was believed that all powers of a government must reside in one person or group of persons located at one place. It was felt that if the power to decide is dispersed, it would not be possible to take quick decisions and to enforce them. But these notions have changed with the emergence of democracy.... hope it would be helpful✌

What is the series combination? Three resistance R1, R2 and R3 are connected in series.show that three equivalent resistance R= R1, R2 and R3

Posted by Md Tanveer 5 years, 3 months ago

CBSE > Class 10 > Science

1 answers

Utsav Kumar 5 years, 3 months ago

The set of resistors in any way is called the series combination. Connecting resistors of resistance R1 , R2 and R3 , we saw that, I in circuit is same but V in circuit = V1 + V2 + V3 Applying ohm's law, I/Rs = I/R1 + I/R2 + I/R3 This gives, Rs = R1 + R2 + R3 Hence proved that the equivalent resistance in series is equal to the resistance in the given resistors.

Utsav Kumar 5 years, 3 months ago

We know that, A+ B+ C = 180° B+C = 180° - A Dividing both sides by 2 B+C /2 = 90° - A/2 Taking cos on both sides, cos(B+C/2) = cos(90° - A/2) This gives, cos(B+C/2)= sin(A/2)

Describe in brief what happens to zygote when it gets implanted

Posted by Venkataramana Shenoy 5 years, 3 months ago

CBSE > Class 10 > Science

1 answers

Yogita Ingle 5 years, 3 months ago

The zygote formed after fertilization in the fallopian tube is implanted in the uterus. It divides repeatedly to form a mass of cells known as an embryo. This embryo gets attached to the inner layer of the uterine cavity, i.e., endometrium. It thickens every month and is supplied with blood to nourish the embryo. Soon it gets covered by rapidly dir.iding uterine cells. This leads to pregnancy.

Within a span of some months, the embryo starts developing limbs and begins to resemble a miniature human being. When all body parts of the embryo can be recognized, it becomes a fetus. When this fetus is fully developed, the mother gives birth to the baby.
