how many units of energy would there need to be in the first trophic level to end up with 1000 units
One million energy units would there need to be in the first trophic level to end up with 1000 units.
This is because only about 10% of the energy is transferred to the following trophic level. The remaining energy is released as heat energy during respiration, one of several ways it leaves the food chain. Life processes make use of it (eg movement)Energy is lost as metabolic heat when an organism from one trophic level is consumed by an organism from the next level, which causes energy to diminish as it goes up the trophic levels. The efficiency of energy transfer between trophic levels is measured by a term called trophic level transfer efficiency (TLTE).

when during the cell cycle are chromosomes visible? question 26 options: a. only during interphase b. only when they are being replicated c. only during cell division d. only during the g1 phase
The cell cycle is the process through which cells develop and divide. The procedure is divided into two stages. Only during cell division are the chromosomes visible.
The cell cycle consists of a series of steps in which chromosomes and other cellular material are replicated to create two copies. The cell splits into two daughter cells, each of which receives a duplicated copy of the material. The cell cycle is completed when each daughter cell is surrounded by its own outer membrane.
The various stages of the cell cycle include: Interphase - This phase includes the G1, S, and G2 phases. M Phase - This is the mitotic phase, divided into prophase, metaphase, anaphase, and telophase. Cytokinesis – At this stage the cytoplasm of the cell divides.

Metabolic pathways in cells are typically far from equilibrium. Which of the following processes tend(s) to keep these pathways away from equilibrium?the continuous removal of the products of a pathway to be used in other reactionsan input of free energy from outside the pathwayan input of heat from the environmentThe first and second listed responses are correct.
The continuous removal of the products of a pathway to be used in other reactions and the input of free energy from outside the pathway
Metabolism is an ongoing process that occurs in all living organisms. To keep the organism operating and in equilibrium, the products of one route become reactants for another. Metabolism does not attain equilibrium because cells cannot operate in the absence of reactants and products. Metabolism imbalance will always be necessary to keep the reactions going. This is also due to the interdependence of the responses.
Because they are open systems, cells sustain disequilibrium. Because of the continual movement of resources into and out of the cell, metabolic pathways never attain equilibrium. A cell is an open system that constantly changes molecules and energy from its surroundings. If a cell is not in an open system, it cannot exchange nutrients or even other molecules with other cells and hence has no work. This can result in apoptosis and function failure. As a result, a cell is in an open system, and its metabolism is always out of balance.

DNA stores the genetic instructions transferred from one generation to the next. What is DNA?
DNA stands for deoxyribonucleic acid, and it is the genetic material found in all living organisms.
DNA is composed of two strands of nucleotides twisted together in a double helix. Each strand is composed of four different nitrogenous bases: adenine, guanine, cytosine, and thymine. These nitrogenous bases form pairs, with adenine always pairing with thymine and guanine always pairing with cytosine. The order of these nitrogenous bases is what makes up the genetic code, which is the set of instructions that tells cells what to do.
DNA plays a major role in the transfer of genetic information from one generation to the next. Every time a cell divides, the DNA is copied so that a copy of the genetic instructions can be passed on. This is how genetic traits are inherited. All of the cells in the body contain the same DNA, but only certain genes are expressed in different cells. For example, skin cells contain the instructions to produce skin proteins, while muscle cells contain the instructions to produce muscle proteins.

for a species with a haploid number of 23 chromosomes, how many different combinations of maternal and paternal chromosomes are possible for the gametes based on the independent assortment of chromosomes during meiosis? for a species with a haploid number of 23 chromosomes, how many different combinations of maternal and paternal chromosomes are possible for the gametes based on the independent assortment of chromosomes during meiosis? 23 about 1,000 about 8 million 46
Different combinations of maternal and paternal chromosomes are possible for the gametes based on the independent assortment of chromosomes during meiosis are 2.3*10^22.
During meiosis, the chromosomes are randomly divided into the gametes. For a species with a haploid number of 23 chromosomes, there are 23 chromosomes in each gamete. Since meiosis involves the separation of homologous chromosomes, the maternal and paternal chromosomes separate independently of one another. In order to determine the number of different combinations of maternal and paternal chromosomes that are possible for the gametes based on the independent assortment of chromosomes during meiosis, we can use the formula for a binomial coefficient (n choose k), which is:
(n choose k) = n! / (k! * (n-k)!)
Where n is the total number of chromosomes (23) and k is the number of chromosomes from one parent (23/2 = 11.5).
So the total number of different combinations of maternal and paternal chromosomes that are possible for the gametes based on the independent assortment of chromosomes during meiosis is (23 choose 11.5) = 23! / (11.5! * (23-11.5)!) = 23! / (11.5! * 11.5!) which is approximately 2.3*10^22
