Komodo dragons (a lizard species) and red-tailed boas (a snake species) are both reptiles. They share a common ancestor population that lived about 250 million years ago, but they have been separated in different environments, with different food sources, for millions of years. Komodo dragons and red-tailed boas have some shared structures. They also have some differences in their structures.



1.Why do Komodo dragons and red-tailed boas have some shared structures and some different structures?

Answers

They have similar characteristics and structures because they are both reptiles and came from a common ancestor. That meant that, going back in time, both of these creatures were once one common, ancestral animal. Once the animals were put into different environments, they changed and evolved overtime in order to adapt to the challenges in the habitat specific to them. But, because they come from a common ancestor, they started from the same ‘base’, and will still share similarities today.

Komodo dragons and red-tailed boas have some shared structures because they both evolved from a common ancestor population that lived about 250 million years ago.

What is the difference has come over the time in these species?

Over time, as these two species separated into different environments with different food sources, they underwent separate evolutionary trajectories that led to differences in their structures. However, many of the underlying genetic and developmental mechanisms that produced their ancestral structures are still present in both species.

For example, both Komodo dragons and red-tailed boas have scales, which are a common feature of reptiles. Scales serve to protect the skin from abrasion and injury, as well as to reduce water loss. They also both have a vertebral column, which provides support for the body and protects the spinal cord.

At the same time, Komodo dragons and red-tailed boas have differences in their structures because they evolved in different environments and have different feeding strategies. Komodo dragons are large, carnivorous lizards that use their sharp teeth and powerful jaws to hunt and kill prey, while red-tailed boas are constrictor snakes that use their muscular bodies to suffocate and swallow their prey whole.

As a result, the structures of their jaws, teeth, and digestive systems are adapted to their respective diets and hunting strategies, and differ in significant ways.

Overall, the shared and different structures between Komodo dragons and red-tailed boas reflect both their common evolutionary heritage and their divergent evolutionary trajectories.

How can oil spills affect the ability of sea birds to access resources such as food and shelter? How will other animals that depend on birds for food be affected?

Answers

Answer:

An area affected by an oil spill can become unhabitable for the sea birds' source of food because of toxic poisons and in turn, make it uninhabitable to the sea birds. The animals that depend on the birds for food will have fewer available options for prey and their population may lower. If the area affected by the oil spill has low biodiversity it will have a great effect on the food web.

oil spill can make the environments of the birds inhabitable because its toxic for them, it can also make it inhabitable because their source food will be toxic or dead so they have no access to food. Other animals will be affected if they eat birds. since there are no birds , the other animals that depend in eating the birds simply wont be alive.

hummingbirds have small, weak feet and rely on their strong wings to move from one place to another. Describe how a disease affecting the muscular system would affect the other body systems of the hummingbird.

Answers

The muscular system of an organism controls the organism’s muscles. When a hummingbird’s muscular system is affected, the muscles will become weak from a disease and they will potentially die because they will not be able to survive without the strong support of their legs or any other muscle in its body.
We know that humming birds are animals that strongly rely one their wings to move around because of their extremely week legs.A disease targeting the muscles of a humming bird would be lethal to the bird.This is because muscles work in pairs to move parts of a body and if a humming bird has a disease effecting it's muscles it would prevent it from flying and do reasonable damage to the movement of it's legs and since humming birds have week legs they would not be able to survive in the wilderness and will suffer for time before dying of starvation,thirst, or an attack....

Answers

Answer:

A. Examples of laboratory hazards:

In general, there are three types of hazards personnel may encounter while working in laboratories at the NIH.  

Possible hazards include:

• Biological Hazards – bloodborne pathogens

• Chemical Hazards – carcinogenic, flammable, or corrosive materials

• Physical Hazards – pyrophoric materials, lasers or radiation.

It is possible, even common, for a single laboratory to have types of hazards associated with more than one of  

these categories at once. Engineering controls should be used as primary barriers, functioning to contain the  

hazards. Personal protective equipment (PPE) should be used in combination with engineering controls to  

reduce the risk of worker exposure to laboratory hazards. A risk assessment should be used to determine the  

hazards associated with a particular laboratory or laboratory operation, and establishing which engineering  

controls should be utilized and what PPE should be selected. Information on how to perform a risk assessment  

is described in Biosafety in Microbiological and Biomedical Laboratories 5th Edition. For assistance with  

performing a risk assessment and selecting proper PPE, please contact your Institute's Safety and Health  

Specialist, or the Division of Occupational Health and Safety.  

B. Appropriate laboratory attire, laboratory coats and applicable standards:

While in a laboratory at the NIH for any reason, all personnel must wear appropriate clothing attire that prevents  

direct contact of materials with the skin. Examples of attire that is appropriate includes long pants or leg  

coverings and closed toe shoes. In addition, a task appropriate laboratory coat, as determined by a risk  

assessment, must be worn while performing laboratory operations. Following a thorough risk assessment,  

guidance to the selection of laboratory coats can be obtained from Tables 1 and 2. Table 1 lists the three types  

of laboratory hazards and the applicable laboratory coat material standards. Table 2 provides a more detailed  

description on the application of these standards and examples of laboratory coats that meet these standards.  

Table 1. Summary of laboratory hazards and applicable test standards

Type of Laboratory Hazard Applicable Test standard

Biological Hazards ASTM F1670 (penetration by synthetic blood) and  

ASTM F1671 (bloodborne pathogen exposure)

Liquid or Chemical Hazards AATCC Method 42 (resistance to the penetration of  

water by impact) and ASTM F903 (liquid chemical  

barrier)

Physical Hazards NFPA 701 or 2112 (flame propagation tests)

The standards listed in Table 2 serve as standardized testing methods to determine protection levels of materials  

against certain hazardous or hazard surrogates. These standards should be considered when selecting a  

laboratory coat material when working with the hazards that correspond to the applicable hazard or hazard  

surrogate tested. These testing methods only test the material and do not test the complete laboratory coat  

making it important to consider characteristics of the laboratory coat such as seams, stitches and where the  

openings, snaps or buttons are located when selecting a laboratory coat. A complete description of the  

standards can be viewed by contacting your Institute's Safety and Health Specialist,

convergent, where plates move into one another, divergent where plates move apart; and transform, where plates move sideways in relation to each other. At a Convergent boundary continental crust is created and oceanic crust is destroyed and it’s a slow process. At a divergent boundary new crust is generated as the plates pull away from each other and it’s a slow process. At a transform boundary crust is neither produced nor destroyed as the plates slide horizontally past each other and i believe it’s fast.

What could you make or do to make sure your bean plants stay upright and don’t fall down?

Answers

Answer:

I got this off of g o o g l e

Explanation:

I put pairs of small fence posts (one on each side) down the row. I then tied twine to the fence post and ran it on either side of the plants. This keeps them from falling over to the side. If you plant thick enough they won't fall to the front or back.

Seedlings fail to emerge. Several possible causes: (1) Beans are a warm weather crop and seed may rot in soil less than 50° to 60° F. Delay planting until the soil has warmed; (2) Soil is heavy or crusted; seedlings may not be able to push through. Add aged compost to the planting bed; cover seed with light compost mulch; (3) Seed was sown too deep or not deep enough. Beans planted in spring 2 inches deep or more may rot and fail to germinate. Beans planted at the end of spring or in summer may dry out and die if sown less than 1 inch deep. Plant beans about 1 inch deep in early spring; 2 inches deep later in the season
