All of its cells are electrically connected via gap junctions. All of its cells are sparsely distributed in the extracellular matrix.
Answer:
Connective tissue is a group of tissues in the body that keep the body and its organs in shape while also providing cohesion and internal support.
All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.
What is connective tissue?
Tissue that sustains, protects and provides structure to other tissues and organs in the body. Connective tissue also stores fat, permits the movement of nutrients and other substances between tissues and organs, and allows the repair of damaged tissue. Connective tissue exists created up of cells, fibers, and a gel-like substance.
Connective tissue is discovered in between other tissues everywhere in the body, including the nervous system. The three outer membranes (the meninges) that surround the brain and spinal cord exist composed of dense inert connective tissue.
Connective tissues bind systems together, form a framework and support for organs and the body as a whole, store fat, transport substances, defend against disease, and assist restoration of tissue damage.

Dynamic equilibrium
Genetic manipulation
Material cycles
Natural selection
Answer:
Natrual selection
Explanation:
your welcome girlies <333
The concept illustrated in the flowchart is Natural selection. The correct option is 4.
What is natural selection?Natural selection is the process by which species evolve over time as the prevalence of certain traits increases or decreases in a population.
Natural selection, the mechanism by which species evolve over time, is depicted in the flowchart.
Overproduction of offspring causes competition for limited resources, resulting in a struggle for survival.
Based on their inherited characteristics, some people are better equipped to survive and reproduce than others.
These people are said to be "fit," and they are more likely to pass on their positive traits to their children. These advantageous traits become more common in the population over time, causing changes in the species as a whole.
Thus, the correct option is 4.

Your question seems incomplete, the probable complete question is:
Though plants, fungi, and prokaryotes all have cell walls, we place them in different taxa. Which of these observations comes closest to explaining the basis for placing these organisms in different taxa, well before relevant data from molecular systematics became available?
Answer:
Due to other differences.
Explanation:
The plants, fungi, and prokaryotes all have cell walls, we place them in different taxa because of the other differences such as mobility, mode of nutrition etc. Plants and fungi are not mobile means can not move from one place to another whereas prokaryotes are mobile. Fungi and prokaryotes are heterotrophs means that feed on other organism whereas plants are autotrophs means make their own food. There is also difference in their cell wall i.e. the cell of plants is composed of cellulose, the cell wall of prokaryotes especially bacteria is composed of peptidoglycans and the cell wall of fungi is composed of chitin.

2) ¿Cuál de los siguientes hechos no es una evidencia de una reacción química? a) Presencia de un catalizador b) Cambio de color d) Liberación de gas
Answer:
a) Presencia de un catalizador
Explanation:
Los dos tipos de cambios que experimentan las sustancias en la química son cambios químicos y físicos.
Un cambio físico es un cambio es un cambio en el que la sustancia cambia en su apariencia o su forma de una manera que es reversible y en la que no se forma una nueva sustancia.
Un cambio químico es aquel en el que hay un cambio en las sustancias presentes y se forma una nueva sustancia.
La evidencia de que ha tenido lugar un cambio químico incluye
1) La formación de un precipitado a partir de la mezcla de sustancias.
2) Un cambio en el color de las sustancias.
3) Un cambio en el olfato (que desprende un olor) o en el sabor.
4) La sustancia produce luz (brilla)
5) El volumen total cambia
6) Cambio de temperatura (la mezcla se calienta o enfría)
Por lo tanto, la presencia de un catalizador, que es una sustancia que no participa en una reacción pero aumenta la velocidad de reacción, no es evidencia de una reacción química.

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.
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.

I think the reservoir ( a human,animal or non living such as soil where the infectious agent normally lives)
secondly the mode of transmission,there are some modes of transmission that allow the pathogen to enter quickly and some that make the process slow.

After phosphates and nitrates have entered a water
system, identify the correct steps of Eutrophication.
I. Oxygen levels drop
II. Underwater plants die
III. Fish and invertebrates die
IV. Algae grows rapidly
A. II, III, IV, I
B. IV, II, I, III
C. I, III, IV, II
D. III, II, I, IV
After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.
Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.
Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:
Algal bloom: the nutrients facilitate the rapid growth of algaeThe bloom of algal species results in the death of underwater plants as a result of inadequate light.The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxiaTherefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

Explanation:
STD is an acronym for sexually transmitted disease and it can be defined as diseases that are easily transmissible or contractable from another person through sexual intercourse. Thus, STD spread from an infected person to an uninfected person while engaging in unprotected sexual intercourse. Some examples of STDs are gonorrhea, chlamydia, syphilis, HIV, HPV, etc.
Generally, contracting STDs has a detrimental effect to a patient because it causes an opening (break) or sore in the body of the carrier (patient) and as such making them vulnerable to diseases that are spread through bodily fluids e.g human immunodeficiency virus (HIV), Hepatitis, staphylococcus, AIDS, etc.
1. Syphilis: can cause sores, rashes, dementia, or blindness.
2. Gonorrhea: can cause burning urination and infertility
3. Chlamydia: similar to gonorrhea but more likely to be carried unknowingly
