Why do living things share fundamental characteristics
Ghella [55]

Answer:

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

Life processes are important to carry out daily life activities. They help to produce energy and maintain homeostasis in the body. The life processes help a body survive with the changes in the environment.

The diagram represents a model of DNA replication.
mr_godi [17]

Although there is no attachment, the best answer would be option B.

DNA replication occurs in opposite directions along a strand of DNA.

The leading strand is replicated continuously in the 5' to 3' direction towards the replication fork.

The lagging strand is replicated discontinuously in the 5' to 3' with segments of DNA known as Okazaki fragments.

Two characteristics about spiral galaxy and elliptical?
PilotLPTM [1.2K]

Answer:

 Elliptical galaxies, such as M87  have very little gas and dust. ... Both the largest and the smallest known galaxies are elliptical. Very large elliptical galaxies can reach 300 million light years in diameter. Dwarf ellipticals, which are very common, may contain only 1/100,000th as many stars as the Milky Way!

 Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.

A plant population produces many seeds. that if a population of plants is currently 30 individuals, and rmax= 12 plants/month, t
LiRa [457]

Answer:

\frac{dN}{dt} = 14130

Explanation:

Logistic growth is a measure of continuous growth of a population of individuals in such an environment where the resources are limited. Such type of growth pattern has a characteristic growth curve which is S-shaped or sigmoidal.

The equation for logistic growth is as follows -

Change in population size = \frac {dN}{dt} = rN(K- \frac {N}{K})

Where,

N = size of population

r = intrinsic rate of increase

K = carrying capacity

The values of r, N and K are given in the question as 12, 30 and 40 respectively.

So,

\frac{dN}{dt} = 12 \times 30(40 - \frac{30}{40}) = 14130
