Review the chart, which shows the population sizes of three African animals in 1990 and in 2000. 1990 → 2000
Lions . 100,000 .→ 47,000
Cheetahs 50,000 → 7,500
Zebras 15,000 → 2,500

Which explanation is best supported by the numbers in the chart?
A)Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetahs.
B)The dwindling zebra population has led to the decline of the predator lion and cheetah populations.
C)Overhunting of lion and cheetah populations has led to a decline in the food source population.
D)Lion and cheetah populations compete for the food source of zebras, and cheetahs outcompete lions.

Answers

Answer 1
Answer:

In the given scenario, lion and cheetah populations compete for the food source of zebras, and cheetahs outcompete lions. The correct option is D.

What is population size?

The number of people in a population is referred to as its population size. The average number of people per unit of area or volume is referred to as population density.

In the given scenario, as the population of zebra is declining, it can result in competition between lion and cheetah in which cheetahs outcompete lions.

Thus, the correct option is D.

In the pedigree below, squares represent males and circles represent females. Individuals who express a particular trait are represented by shaded figures. Which of the following patterns of inheritance best explains the transmission of the trait? A) Sex-linked dominant
B) Sex-linked recessive
C) Autosomal recessive
D) Autosomal dominant

Answers

The patterns of inheritance best explain the transmission of the trait is Autosomal dominant. Thus the option D is correct.

What is the autosomal dominant ?

The term refers the genetic characteristics of the disease that lies in the chromosome. The dominant means the single copy of the disease that is linked by mutations and causes the disease. They include disease like Huntington's disease, neurofibromatosis, and polycystic kidney disease.

"Autosomal dominant" patterns of inheritance best explains the transmission of the trait.

Answer: Option D

Explanation:

In single-gene disorders there are several fundamental inheritance modes: autosomal dominant, autosomal recessive, X-linked dominant and X-linked recessive. Nevertheless, these patterns will not be observed by all genetic conditions, and other unusual inheritance mechanisms such as mitochondrial inheritance occur.

Autosomal dominant is an inheritance pattern in which an individual affected has one xerox of a mutant gene and one normal gene on a pair of autosomal chromosomes. Autosomal dominant is one of many ways in which families may transmit a trait or disorder. If one get the abnormal gene from just one parent in an autosomal dominant disorder, than he/she can get the disease.

An anthropologist finds a 29 cm humerus in a remote site at a mountain resort. There was a missing person's report for a woman (approximately 5' 5'' tall) placed just about a week ago. Could this bone possibly belong to her? Why or why not?

Answers

Answer;

The humerus most likely does not belong to this woman

Explanation;

-When this value for the MLH is plugged into the white female equation, the height range is 150.96 cm - 159.86 cm. This converts to 4.95 - 5.24 ft (there are 2.54 cm in an inch, so you simply divide the number of centimeters by 2.54 to convert). If this value is plugged into the black female equation, the height range is 149.74 cm - 158.24 cm.

-This converts to 4.91 - 5.19 ft. Neither one of these heights is as tall as 5'5" (which in decimal form converts to 5.42 ft.), so the humerus most likely does not belong to this woman (although it could, since we found that the humerus is not the best indicator of height).

Answer:

The answer would be - no.  

Explanation:

In the forensic anthropology, the anthropologist can measure the height with the victim's femur or humerus bone. The value of the height can be measured by the simple method which is, measuring the humerus bone in inches and multiply it with the 2.6 and add 65 in the case of the female victim.  

This value will be the estimated value of the height of a female individual. The value of the MLH is put in in the white and black women equation the height range is not found as tall as 5 ft 5 inches.

Thus, the correct answer is - no.

Answer: Sustainable development

Explanation:

  • Sustainable development is the use of resources in the present in such a way that it does not compromise with the needs of the future.
  • This definition of sustainable development is derived from the 1987 Brundtland Report.
  • The concept was introduced in the the report to combat the problems caused due to industrialisation and population growth.
