Living things grow and develop.how are these two features of life different?

Akimi4 [234]

Basically, when something grows it demonstrates an increment in something you can check. A tree can grow. That implies that it adds to its tallness. We can number the inches it has developed. An association can develop, adding individuals or different gatherings to itself. These are numbered effortlessly. Benefit can grow, including cash in diverse ways. Growth without anyone else's input, in any case, can't gauge advancement. If we take a gander at the stature of a man, it might be anything but difficult to accept they are a grown-up. When I was in evaluation school, a comrade of mine was more than six feet when he was only 11 years of age. If we take a gander at how tall he was, he would be viewed as a grown-up. Be that as it may, at that age, my comrade wasn't sufficiently created in his reasoning, not to mention passionate growth, to be viewed as a grown-up. There is an enormous difference. Without a waste of time, what is development? Development envelops numerous things however it is demonstrated by the subjective change of circumstances. This implies that as something adds to the nature of the entire makes strides. As a tree creates, it won't just develop, additionally have the capacity to replicate, like a natural product, be sound and proceed with growing. Hopefully, this clears up the most evident contrasts between the term development and growth and can direct you to a few assets that will help you toward better comprehension!

astraxan [27]

Complete question:

17. In the 1950’s a young woman sued film star/director Charlie Chaplin for parental support of her illegitimate child. Charlie Chaplin’s blood type was already on record as type AB. The mother of the child had type A (AO) and her son had type O blood (OO).

a. Complete a Punnett square for the possible cross of Charlie and the mother.

b. The judge ruled in favor of the mother and ordered Charlie Chaplin to pay child support costs of the child. Was the judge correct in his decision based on blood typing evidence? Explain why or why not. *refer to any Punnett squares to support your answer.

Answer:

The judge committed a mistake in his decision. There are <u>no chances</u> for this couple to have a child who has 0 blood type.

Explanation:

<u>Available data:</u>

Charlie Chaplin’s blood type was AB
The mother of the child had type A (AO)
The son had type O blood (OO).

Cross: Charlie Chaplin x The Woman

Parental) IAIB x IAi

Gametes) IA IB IA i

Punnett square) IA IB

IA IAIA IAIB

i IAi IBi

F1) 1/4 = 25% of the progeny would have IAIA genotype, blood type A

1/4 = 25% of the progeny would have IAi genotype, blood type A

1/4 = 25% of the progeny would have IAIB genotype, blood type AB

1/4 = 25% of the progeny wouldl have IBi genotype, blood type B

According to the results of the cross observed in the Punnett square, there are no chances for this couple to have a child who has 0 blood type.

Blood type 0 can only be produced by two recessive alleles i, one inherited from each parent. The mother could provide the recessive allele because she is IBi, but Chaplin could not pass to his progeny any recessive allele.

The judge committed a mistake in his decision.

How can you see change over time using topographic maps and satellite images?

Alexus [3.1K]

Topographic maps and satellite images

Explanation:

A topographic map represents earth's surface features like land forms and structures, rivers and lakes, mountains and hills, elevations and other natural features along with man-made artificial features like cities, buildings, monuments, roads, bridges etc. These are formed by contour lines.

Topographic maps are printed with revision dates to observe the changes happening on the Earth's surface. Various land forms keeps changing due to natural and man-made causes and these needs to be updated accordingly to provide accurate details.

A satellite image provides details of the earth aerially from space. These provides details of a land form or any earth structure currently.

By comparing with older satellite images or topographic maps with the current one, the changes which occurred over time can be observed.
