explain how a pond freezing over relates to the properties of water and why that is important to the survival of the organisms that live in that pond.

Answers

Answer 1

Answer:

As the water cools, the molecules in the water slow down to turn into ice.

As this happens the water stagnates and organisms in the water go into a hibernation to avoid freezing or starving

define uniform and non-uniform velocity. How much acceleration is produced on an object at uniform motion, why?​ Pls answer my question anyone pls!

Answers

Answer:

when a body covers equal distance in equal interval of time with a known direction, small the interval may be then velocity is said to be uniform velocity.

when an object covers unequal distance in a specified direction is said to be non-uniform velocity.

It produce zero acceleration as acceleration is defined as the rate of change of velocity per unit time. So, if the body exhibit uniform velocity,then the rate of change of velocity (dv=0) will be zero.

An actin-binding protein called cofilin binds preferentially to ADP-containing actin filaments rather than ATP-containing actin filaments. Based on this preference, which is true? Question 7 options: Cofilin binds to the plus ends of treadmilling actin filaments. Cofilin competes with profilin for binding to actin. Cofilin binds to older actin filaments. Cofilin binds to the plus ends of actin filaments.

Answers

Answer:

Cofilin binds to older actin filaments

Explanation:

Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.

Jim has become particularly interested in the genetic basis of cancer and has spent considerable time reading published papers about oncogenes. He learned that as early as 1972 researchers suggested that mutations in proto-oncogenes caused by carcinogens can convert them to oncogenes. He asked you to answer a couple of questions about this because he did not have the biology background to totally understand. Jim learned that some cancer cells produce more growth-stimulating proteins than others. What would you give him as a plausible explanation

Answers

Answer:

Proto-oncogenes may have mutated to become oncogenes in these cells

Explanation:

Cancer cells are characterized by key properties such as an abnormally rapid rate and poor differentiation. Proto-oncogenes are genes that lead normal cells to become cancer cells when they are mutated. Many proto-oncogenes are involved in the control and progression of the cell cycle, and apoptosis (programmed cell death) pathway. Some examples of protooncogenes include 1-the Ras gene, which is required for differentiation, growth, and cell survival (mutations of this gene have been reported in pancreatic cancer, lung cancer, colon cancer and thyroid cancer), 2-the Myc gene (mutated in Burkitt's lymphoma), 3- the Her2 receptor (a receptor kinase associated with breast cancer), etc.

H20fall, how do I find out how much salt is in my pool?

Answers

A very peculiar question, kind sir

I supposed one can start by allowing his pool water to evaporate in the blazing summer heat in order to separate the solute (salt) from the solvent (water). After the separation, the obtained mass of salt can be measured on a scale in order to determine the concentration of salt that is present within thy swimming pool. This technique is the most classic of all, and is also the most expedient way to extract salt from water.

use numbers to arrange the events of a demographic transition in order in which they occur

is this correct?​

Answers

the order is 1,4,2 then 3.

(DTM) is defined by a country's death rate dropping quickly while its birth rate staying high. Because of this, a nation in Stage 2 will show an increase in its general population—not because the birth rate is rising, but because births outnumber deaths.

What are the different events of a demographic transition?

The demographic transition model was initially proposed in 1929 by demographer Warren Thompson. The four stages of the paradigm are pre-industrial, urbanizing and industrializing, mature and post-industrial.

Stage 1: Slow population growth is caused by high birth and mortality rates. Stage 2: While the birth rate stays high and the death rate declines, population growth accelerates. Stage 3: Population growth slows as the birth rate starts to decline.

Therefore,  1,4,2 and 3. It is correct events of a demographic transition in the order in which they occur.
